Yesterday while watching the Complete Kiteboarding Guide from Naish I saw the UDS system in action for the first time. I had never taken any notice of it because my Modified Airush Bar worked perfectly well for my "old school" riding style. Why change a good thing :)
I basically ride with my bar set so that the back & front lines are equal length with kite fully sheeted out/powered up! (I think it's called - blocked) anyway I depower after I complete a jump to go back upwind and power up just before I jump. After about 3 - 5 months my Airush Depower strap needs replacing.

The UDS systems seems to work like this without needing to "pull the strap" simply by un-hooking & then hooking in when you need it.
Comments anyone?
Thanks
