Her bag is definitely setup for someone with good clubhead speed. While a lot of clubfitters will say that shafts are mostly feel and weight (not flex) is the most important factor, it is still a bit surprising to see her playing NS Pro 950 R-flex irons given how fast she swings. I'd guess that even her driver shaft fees quite soft, given it is the 50 gram version (torque rating is much higher than other tip stiff designs).

    I guess it's possible that she hard-stepped the iron shafts. The NS Pro 950's are very high launching. I played them in regular for years. 'Good if one has a smooth transition, which she seems to have, even though she's swinging hard. Heck, doesn't Jim Furyk play R flex?

    It's possible they are hard-stepped (like Furyk's). At the end of the day, I guess it doesn't really matter as long as she's hitting the ball well. But I thought it was an interesting observation nonetheless given her speed and that shaft's profile.



    Most mid-handicap amateurs seem to be the other way - pick the stiffest shaft you can load on your hardest/best swings and assume that will happen on every swing (even though it doesn't).

    That's why I enjoy the women's game. I learn a ton. 'Everything from tempo to course management to equipment.

    That's my strategy. I'm an idiot!

    Thanks for the info regarding hard-stepping - never heard of this before, so "ye olde gügle" provided the necessary info. Interesting concept.

    Soft stepping is the opposite process, resulting in less flex. Basically, one uses the shaft for the next iron. For example, to soft step a 9 iron, one would use the 8 iron shaft. The 8 iron would use the 7 iron shaft, etc. A hard stepped 9 iron would use the PW shaft.

    Hard stepping makes the least sense (to me).

    Many shafts (eg the popular KBS Tour) sets still have 9-iron/wedge shaft as the PW, GW shafts.

    The only reason I can think of them doing it is to sell some specialty wedge shafts...

    In hard stepping, you’ll not only put that shaft in the wedges and 9-iron but also 8-iron and possibly 7-iron if hard stepping x2.

    I'm not a club builder, but generally I agree (i.e. soft stepping (even 2x) is slightly better, as it preserves the flex progression in the shorter clubs).



    I guess reasons why it may not matter much:

    a) TT DG has the same 9-iron / PW shaft and no one really complains about these shafts being the same in a straight-in set.

    b) The PW/GW are likely used for some less than full shots. If the clubhead weight/swing weight in these clubs is slightly higher it may make these shafts play slightly softer (not a bad thing). I can see how you still have issues with the 9-iron though.

    c) 95% of golfers probably couldn't tell the difference of the same shaft being in the 8-iron - GW if you didn't tell them (or let them look at the step pattern).

    My two thoughts on why she has R flex irons shafts in the 790 and 760. They are fairly low spinning, so she plays Rs to get an optimized launch-spin combination. Even on good hits with a lot of club head speed they pull spin off, some of the big hitters on youtube have issues with these irons getting really low spin from rough, so the extra launch and slight extra spin will help her keep the set playable from the rough and other not so great lies.



    She ends up switching to 105 S in her wedges, and they dont have the low spin characteristics for the 790/760s. I think its an optimization/playability thing.

    It's an interesting observation - I never thought about how the shaft was matching up with the vastly different heads that are out there these days.



    The weight progression in the Modus 105 S seemed "normal" vs the 950s. The stiffer flex is a bit contradictory vs. what is "recommended" these days. However, a while back I believe many people used to recommend a stiffer wedge shaft, as control was key. But then Titleist / Vokey started pushing the S200 option (unclear if that's best or what suited business economics of buying all the S300 rejects from TT), and now either the same shaft or some combination of heavier / softer is what's perceived as best.



    Honestly, it seems like whatever shaft is in a SW or LW (i.e. wedge used for mostly less than full swings) is all feel relative to your iron shafts. For example, I think Koepka is playing X100 / S400. If I followed the same logic I would be playing R Flex / Senior Flex. But to make a LW go 75 yards we are both swinging the club at roughly the same speed - it just happens to be a full swing for me and a 1/2 flick for him. My point being I'm not sure if the force on the shaft is that different compared to the difference is flexes. In contrast, when we each swing a 6-iron there is a huge difference.

    Love her setup.



    Setup is almost identical to mine.. My equipment s are decades older..



    I use NS Pro 950 S on my irons.. love the way they feel...





    I moved away from heavy shafts...
