I've seen very few refrences or experiences with this one, yet it could be pretty cool. I'm in a few sports teams (rugby/football/mountainbike team) and I know the mindset you have going in and through the game/race/etc. has a massive impact on how you do, the body is only as powerful as the mind. Used right, and along with JuiceIT, this could be a pretty strong dose, so I'm pretty curious.
