Can't say wrt int, but sr is accurate.
Big fan of Geppetto, highly recommend the sticks. They are close to top of the line sticks in performance, custom options are amazing.
Unfortunately, just saw on his insta this morning that the nhlpa sent him a cease and desist email re posting pics of NHLers and using player names for his curves. I get the second one, but he posts from Getty images, so not exactly sure what authority the NHLPA have over that.
Anyway, someone above mentioned his way of describing curves, which I agree, it is a bit odd. I recently have been using a stack of Warrior W10 retail Gionta curves and love them. Asked his rec and he suggested Gino pro, which I have and can say that the Gionta has a lower lie and a way bigger toe hook than Malkin. From his visualizer, it looks to me like Hossa, Kovy or Spezza are much closer to W10. The other thing that irks me is that he changes the lie, often making it higher than the actual pro curve.
