You won't go wrong with either of the Rocky Mountains. The Snyper flies slightly better than the Gator, but the Gator makes a heck of a gash. By the way, did you know they are making a 3 blade Snyper (Snyper XP 3) to be available at the end of June? Might keep that in mind...
Personally, I would stay away from the Hypershock.
