For the new kites, I haven't flown them yet, so can't comment. I just hope they aren't too different than the Bandit 6... that is such a sweet kite.
I did get a chance to ride the new HRD Trax Carbon twin tip. I've been kiting a little over 12 years, and mainly ride surf boards these days. I'll pull out a twin tip from time to time, depending on the conditions. I really had fun on this board. It just gets up on a plane really fast, and is super smooth in the water. Lots of pop, soft landings, no spray in my face, fast, and just overall really comfortable to ride. I have no idea the technical stuff behind the new rail shape, but it works. I really liked this board.
