I am coming from the 2020 model P770s. I did not really notice the rounder toe on the Srixons until you said this. I can see it now in the pictures. It's never once crossed my mind on the course.
I ended up dropping out of the Club championship due to some schedule conflicts and very poor weekend weather forecast. I have gotten 3 more rounds in since then though. My swing is not in a good spot right now and I truly think that has been advantageous to my testing. As @robbie91 mentioned, the Srixon irons are very forgiving. On my bad days with the P770s I would see some massive curvature to the ball, and significantly short thin shots. The Srixon's have left me in much better spots and I can usually get up and down so the scores don't balloon too much. The pure shots just feel absolutely fantastic. The Bad shots don't feel nearly as harsh as they did with my P770s.
The V-sole is the real deal. My divots are shallower and the club just pops out of the turf better. Last week I caught a terrible lie in the first cut. My ball was sitting in the front of a pretty deep divot. I decided to swing really steep and try to get it out the best I could. This was the harshest impact I've felt to date with the Srixon's and it wasn't terrible. The ball shot up out of the divot and landed just left of the green, pin high. It was a great outcome for really poor luck.
As far as durability, the irons are holding up great. I don't see a ton of bag chatter and luckily I have not hit any rocks or roots.
For distance; I'm still seeing 5-10 yards more carry distance than my P770s and ZERO flyers. I have hit thousands of balls with these irons now and not once have I had a rocket ship off the face like I would occasionally get with the 770s. If the ball was perched up or I caught it high on the face it would go 15-25yards further than normal and that was extremely frustrating, especially when I played courses with zoysia fairways. The Srixons absolutely don't do that. Now, I will get a little flyer out of a bad lie but it's fairly predictable. If it looks like I'm gonna have grass between the ball and club face, I'll just go down once club or choke up a little and it's not an issue. I can remember one occasion with the P770s where I had 170yrds to a front pin on a zoysia fairway. I was hitting the ball really well that day and 170 was an absolute perfect number for my 8 iron. I high a high, towering draw dead at the pin. I thought it was going it the whole time until It flew the whole green by 10 yards and I had a downhill chip shot that resulted in a bogey. That shot must have gone 30 yards further than normal.
I'll put together a more formal review in the next few days with some updated pictures. Robbie said, these irons are firmly in my bag for the foreseeable future.
