I believe the jpx923 forged stock loft on gw is 49, I had it bent to 48. I do realize it's not just the club loft that affects distances. I am working very hard on using practice swings to get a feel for turf interaction, swing path and tempo.
I have pretty much decided to really scale back my swing effort. I am truly committed to making an easy smooth swing and living with my distances.
I like all my distances except for the gw. I am going to work on it a bit, but in mean time I am looking for a mizuno s23 in 48 deg. When I am inside 80 yards I pretty much use my 56° sand wedge. I feel pretty good about all my distances, just never been happy with gw.
