I use Cabrinha SB's, 2010 models. I've recently tried the Slingshot Rally in a 12 & 10m. I really like the SS but.... First thing I found odd was there was no pump leash attachment on the kite, just the plastic clip to lock the valve. Now, I did use my Cab pump with the ball. Does the SS pump attach to the clip? Second, I always try to fix launch my SB's when alone( CL attached to a fixed anchor). The SS Rally always falls over when I set it to the edge of the window( it's windy). Am I missing something? I watched an online video and I'm sure the kite was started from an anchor point. The SB is very simple to start and land using a fixed point. My local spot has no beach to launch, so a drift launch or anchor launch is the choices.
The SS safety release did jam the first time I tried it but after that it was perfect. It was very easy to flag the kite or relaunch it, something my Cabrinha does not do easily ( the relaunch after the IDS is deployed)
Both kites are really good quality with an edge to SS for there bar and safety system.
