it depends. are you till growing? that might be a little too long, but it could also be perfect if you're charging a lot, and shred hard(which i get the sense that u are). so from what you say on your skiing ability, and agressivness, i think that that could be close to perfect.
have fun with those jjs!
you could also check out the on3p caylors, which would be a sick choice:
join the cult for more info; http://newschoolers.com/web/content/viewcult/id/2788/
either way, caylors or jj's would both be good options.
