Flew the Rhino's a while back. It's been a while, so comparing it would be difficult, but I DO recall that when I flew the RHino, I fealt like I was flying any other kite...as opposed to when I first layed my hands on the 2002 SlingShots. WOW! They were like the second coming of Christ to me. IMPRESSIVE to say the least. I was so impressed in fact, that I started telling people how great they were, SO MUCH, that people started thinking I was being paid to promote them. UNTRUE that is. I LOVE THESE KITES! I swear by them. I am willing to let anyone who can get to me here demo ANY size of them that they wish.
As far as the Aero's...well, I've always been pretty satisfied with my Naish kites, but, in my opinion, they aren't SlingShots by a longshot!
If at all possible, I highly recommend to people that are wanting a new kite to at LEAST try the SlingShots, just to see for themselves what they are capable of.
Team TampaBay Kitesurf took first place in the Big Air/Hangtime contest in Islamorada on SlingShot kites. If memory serves, I think SlingShot kites captured 2nd as well with a Naish Aero taking 3rd.
