So, here we go again with the "made for" shafts.
If I would find a "made for" shaft, like the Fubuki 50Z that came with Big Bertha, that I like very much, I don't think that the "real thing" would fit me...
If the shaft fits you, it's a good shaft for you. Nevermind about the "made for".
I remember Oak Brook - my wife and I used to golf there sometimes. Also played at The Hills in Lebanon last spring when we were up for Easter.
Congrats to your #1 on her ace! Two (at least) by that age is pretty awesome.
