Project X vs PXi stiffness

[WeritoK2]

Hi guys! 
 

How would a Project X 6.0 would compare in feel and performance to a Pxi 6.5? I just took the blackout Project X 6.0 out of my irons because it feels way too stout and hard to load, I have a set of Pxi 6.5 in my eBay cart to give a try but what if it’s the same or worse? 

[Jonesy]

PXi are definitely easier to play with, I had a set of 6.0's which I never really had an issue with but they just didn't have the magic that the normal PX did. For reference though I much prefer the boardy feel of PX, I reckon they feel crisp while the PXi is smooth. 

 

For you though I'd say a set of PXi 6.0's might just be the one, smooth feeling, easy to load, extremely playable shaft. The 6.5's won't be like the PX but they will probably be a tad firmer feeling than the PXi 6.0 but not bad.

I've tried the Pxi in a few different Driving Irons at Golf Galaxy and could actually keep them in the air with enough spin.  I could never do that with the regular PX 6.0 shaft.  About the 5 iron, I lose spin and distance with the PX 6.0.  I don't have that issue with DG s300/s400 or my Modus 125s.  I would consider putting a Pxi in a 3 or 4 DI head if I could find the right one.  It's so much smoother to me.

For the most part, the PXi is just a lighter version of the PX with basically the same profile. It plays about a full flex softer, partially because the PX is so stout and partially because the PXi is a little softer by design. I would look at something like the PXi 6.5 playing Closest to a PX 5.5.  

[Howard_Jones]

Forget the flex letters when comparing PX to PXI, simply sort them by WEIGHT and you know what you have at hand, its that easy really.

IF the PXI shaft you look at is lighter than the PX model you compare it to, its a softer shaft, and opposite.

[Pepperturbo]

I played 120g PX 6.0 "S+" from 2006 to late 2018 or 2019.  At the time I thought going to lighter weight shafts was in my future so I tested a number of different profile but lighter shafts, including graphite at 95g to a set of PXi 6.0 "S+" which are 112g, 6.5 is 117.   

 

All I'll say about PXi 6.0 is they have really nice looking graphics, but they feel nothing like PX.  I had them in another set of irons and put one in 718 T-MB 2i. 

As a result of my fast tempo that never reaches parallel and quick transition, right before impact there was a noticeable clunk of sorts.  I couldn't even hit my 2i without real deliberate change to my approach to hitting the ball.  That clunk was the clubhead miss-hitting the ball.  To eliminate the clunk I had to slow my swing down and reach parallel at the top, and make a nice full transition down deliberately, only then did I hit the ball properly.  Felt weird as hell.   

 

PXi, IMO is for a someone that has a languid swing that reaches parallel and has smooth transition and acceleration.

Shot in the dark, but if you're interested in unloading the PX shafts let me know.  I'm looking for 5-AW but need them to be +1/2" or more.

How would the PXi 6.5 play and what “flex” would it be if I’m to soft step a set once? 

[jimb]

I had a set of 6.0 PXi shafts in my set of 2013 X Forged irons.  I absolutely loved them.  They were definitely not as stout feeling as the PX 6.0.  I have always focused on a smooth transition in my irons and those were perfect for my swing.

[geochitown]

what is the comparison of weight from PX 6.0 to PXi 6.5?

 

I agree that the Pxi must be a softer and different feel than the Px's, so I wouldn't be afraid to go Pxi 6.5.

 

You could easily build a test club (7 iron) straight in (and then if it's a hair stiff, you could soft step it, but a soft step by 1 is not going to be a significant change).

some related threads on Pxi's

 

PX 6.0 = 120 gram
PXi 6.5 = 117 gram
PX 5.5 = 115 gram
PX 5.0 = 115 gram
PXi 6.0 = 112 gram

[geochitown]

why did you pick pxi 6.5's instead of pxi 6.0's?

6.5 all that you could find?

 

what shafts have you used in the past besides px 6.0

 

There was a Howard Jones thread that was sticky'ed in this forum

not sure where it went.

 

Lots of discussion there

Are you saying that PXi 6.5 117g is similar to PX 6.0 120g is similar in flex and profile?

 

Still trying to find equivalent to PXi 7.0 SSx1

The new Project X IO are the PXi replacement.  I'd give the IO a try in 6.5.  Standard PX is different in flex and profile and doesn't really crossover to the PXi.  The closest to 6.5 in the PXi would be 5.5 in the standard PX.

NO, im saying 117 grams is softer than 120 grams, but stiffer than 115 grams...

PX 5.5 115 grams
PXI 6.5 117 grams
PX 6.0 120 grams

Thats how they should be sorted, by weight, NOT flex label
PXI 6.5 is actually a tad softer than PX 5.5....but the "en-changed profile" makes it feel "firmer" and the label tells your mind its "strong enough", but its really a very soft shaft compared to its flex label. PX and PXI DONT have the same EI profile, but its very close.

Howard that's some great info as always you are the patron saint of iron shafts!

 

Would you be able to give me your best bet as most similar to PX compared to PXi 7.0 soft stepped once?

 

From above guessing something around 6.0 in STD PX wouldnt be far of. And funnily enough PX 6.0 in the past before I went into PXi was one of my faves. Or would the slightly smoother profile of LZ be better? Something between 6.0 and 6.5?!?

 

Still unsure if IO from what I've read is actually like PXi.

 

Tender hooks waiting for this reply.

im about to get "rusty" on this, but if we should judge it by BUTT CPM, we say that SS1 is moving butt CPM with 4 CPM average, and even if there is NO constant steps from one PX flex to another, a PXI 7.0 SS1 would be very close to PXI 6.5, only with a higher weight, so PXI 6.5 would be "the closest option".

Since the whole profile on PXI is softer, a PXI 7.0 SS1 would also have standard PX 5.5 strait in as a option, but that would not be as close as PXI 6.5 strait in.

This zone flex datas comes from Tom Wishons shaft profile software, but PXI 7.0 is not present, neither is the standard PX 5.5, but by looking at the others, we get the picture of where they belongs.


 

The LZ version could be a option, sure, but its a more curvy profile with the standard PX as basis, while PXI is "closer" to the standard as profile, only softer with some tweaks all the way, and thats why i suggest that when we compare the standard PX with PXI, we should simply go by its weight. That means if we used weight to compare PXI with LZ, the LZ will feel softer since it has more feel of load and release than the standard PX/PXI profile delivers at the same weight.




PS! The PX LZ is uncut 0.5 SHORTER than PX/PXI, so the official wgt is NOT directly compatible, meaning LZ is close to 2 grams HIGHER than official specs when we compare LZ to PX/PXI, so LZ is "the heavy but softer feeling option" to the others.

I had a set of Callaway irons several years ago with the PXi shafts installed in them.  They were 6.0.  They were very smooth feeling to me and I could feel the shaft load and unload during my swing.  I have also hit the PX iron shafts in 6.0 and they felt very firm to me.  For my swing tempo and clubhead speed, the PXi shafts in 6.0 were a better fit.

So I hit lots PX shafts yesterday in a buddys trackman studio and found for me PX LS 6.0 felt and went the best and 2nd best was PX LZ 6.0 and my PXi was as good as those 2. 

 

I think there may be scope t try some hard or more likely some soft stepping on the LS 6.0 and I could be onto a winner.

 

Wouldnt have got to this point without Howard's info. Didn't try a PX 5.5 but happy with what I've come out with.

Been thinking I wish I had hit LZ 5.5 and then maybe build an iron hard stepped once or twice to get me same weight as I am now at 117g and similar flex. Especially as there is a 36.5 raw shaft in LZ.

Hi Howard can you then confirm which uncut length is considered for instance the 7 iron shaft.

The PXI - PW is 36.50"...do the math

[j-daniel]

Thanks I didn't know if the 36.5" was a SW shaft.

Late to this convo, i know. That being said, i took a hiatus from the game from the age of 24-32. Jumped right in a few years back with the PXi 5.5 on some Apex Pros.

After trying out PX's full lineup i've come to the conclusion that the Tour Flighted Rifle on 6.5 is the right monster for me. Just so damn hard to find.

Classic Rifle 6.0, LZ 6.0 and LS 6.5 were next.

Pxi just has ZERO personality to me and the IO just doesn't handle my Transition.

What a game!
