If there is a player in the NHL using this technology, there is definitely something there. Kronwall isn't trying something out during NHL games. No one is fucking around during an NHL game. As far as I can tell STX still hasn't even gotten their "PureGrip" shaft to the NHL. I would definitely say that seeing #55 wear them took me from being a doubter to someone who would experiment with it for sure if it was affordable for me.
