High speeds vs. tight turns?
So I'm looking to get a new board for this year, and my main goals for this season are to get better at riding faster, and also at trees and moguls. From all the research I've done it seems like it's better to have a long, stiff board for speed and a short, flexible board for tighter turns. I'm also not sure how board shape factors in, although from reading reviews it seems like I should go with some sort of hybrid.
Anyway, I was wondering if based on these things anyone had any recommendations as far as either specific boards or just general specs/technologies I should look for. For reference, I'm 5'9", 150 pounds, budget not an issue. Right now I'm looking at the YES Jackpot which looks like it could be great in trees, but I'm worried how it will hold up if I try for speed.
