They have many, but I only tried about 8. They look at what I'm currently playing and what numbers I'm getting with them. Then they play with weights and such based upon that to dial it in. You can request certain ones if you want, but I just let them bring me what they were thinking would fit me. KBS, Nippon, Rifle, and Steelfiber with a few different weights of each was what they brought out for me.
I actually 'broke' one of their shafts π. The epoxy on their attachment came loose on one of my swings. It was a popular model too, as another fitter came by later looking for it and said to his co-worker 'oh, you broke it'. I proudly said 'no sir, I broke it!' π
