Hey bud! That GP1 looks and sounds bad ass! I can only imagine how it rides and performs. Sorry to hear about you knee but I know the feeling well. I twisted my upper body and heard and felt a pop in my knee towards the end of March. I was on crutches and then limping for over 2 months. it's finally feeling 95% normal. We plan on riding the Superjets this weekend for the first time this season. Hopefully all goes well.
