well if you just got em, ride em and let your self know! no i dont actually...search the bar and see if some one has posted? sorry hope their everything you ever wanted in a ski
the thrusters are kind of stiff, not too stiff though. they have a lot of pop when you go off jumps and its sweet. but after a while, your core will break down and they will be more flexible. but i think they they are a pretty sick park ski.
