The ski I will be putting them on will be the armada alpha 1 2013 1.5 back from middle and all I wanted to know is would it hinder me in the park, they feel a little heavy and it does say speed on it so Im guessing it is for racingv, and they look kinda old, I am 5'11 I am 17 and I weigh 170 and last year I was just starting to slide rails and spin a little bit on jumps but I have ski all my life so I am not amazing but I can make solid turns. I hope you guys can help.
