As IP said, it means nothing. Put them on, flex them, lean on your edges in both directions. Go with what feels best. I currently skate 4-6x week between playing and coaching. I'm in in AS3 PRO, 100k Pro, and Machs. I've also skated extensively in 2xPros, 70k, 80k, AS1. I skate like me in all of them...they just have different fits and feel. Close your eyes whatever makes you wanna go for a slide...that's the one.
