Shazsam (Gomer Pyle reference), OP, I want to have your swing speed!
in my dreams...
Congrats on your game and irons.
That's not accurate. TrackMan and FlightScope measure the clubhead speed. It's not calculated or a guess.
No, it is directly measured. It is not calculated. Only the face stuff is calculated, basically.
I disagree with those fitters about clubhead speed.
Shaft flex has a tempo component. That matters quite a bit when fitting for shafts. A person can have a slower swing but need a stiffer shaft if they have a faster tempo or a quick transition, for example.
I got my new irons today. I actually had to cancel the order put in with Ping when I went back and tested to find that the CFS had equal performance to the KBS shafts for me. I bought a set of them from the store since I need to get in some rounds with them before tryouts in August, and I went out to play some rounds with them. Unfortunately, torrential rain with some hail stopped me after six holes so I didn't get too much playing in with them, but first impressions are nice. On the range there was a noticeable improvement in the dispersion. Picking a target at my PW distance I was able to hit 16 balls in a row on the green with the new club on average and an average of only 12 balls in a row with my old wedge (I rounded these numbers). The clubs were surprisingly easy to hit, nothing like what I'd been led to believe a club advertised on the PING website as a "Tour" iron would feel like. Even on thin shots they held their line with fairly minimal loss of distance. Fat shots tended to dig a little bit more, but that's just because of the thinner sole with a bit less bounce than the Eye 2's. Overall I'm looking forward to getting out and playing a full round with them after I get back from Indianapolis on Saturday (I fly out tomorrow).
It was on the range, so not really an accurate assessment of on-course performance. When you have an ideal lie every time with no pressure it's pretty easy to hit an admittedly large green on the driving range.
