In-flight characteristics of the 2011 Rise are essentially the same as the 2010 model - there was really no reason to mess with a good thing (the Rise has seen significant changes and refinements since its introduction in 2007)! Rather, we focused on small refinements to its construction, and made real improvements to the 2011 bridle and bars.
The 2011 Rise (and Razor) incorporates the new Roll Over Bridle, which when used in conjunction with either 2011 bar, allows the kite to fully depower on its back in a position for quick and easy relaunch after the rider has ejected or ” safetied ” the kite. The kite offers significantly more depower when safetied than older generations of the kite (though many would argue these had more than enough ).
With regards to your question on bar use, you can use either the Freestyle (above the bar depower) or Freeride on the Rise, though we ship the Freeride standard unless a specific request has been made for the Freestyle. The Freestyle bar works very well on the Rise and in fact does offer you full depower and plenty of sheeting throw. As such, I would base your decision on which bar to get based solely on your preference for above vs below the bar depower. The Freestyle bar is definitely more conducive to advanced freestyle, vs the Freeride bar which requires that you be conscious of your stopper position.
