Does anyone actually use the clips that close off the LE bladder to the strut bladders? The only company that has a compulsary shut off is Naish with the Octopus System. Other than that I don't think I've ever shut them off.... ARE THEY REALLY NEEDED? (I hope not as I've removed them now!)
The Naish system, is not like that Martynbone, the valves from the LE to the struts are one way, they do not lock off like normal clips.
In the event of a LE blowout they prevent air from flowing out of the struts, but in the event of any strut blow out or puncture the whole kite deflates. Also if the kite is crashed hard air is forced into the struts through the LE/Strut one way valves and the increased pressure can cause zips and stitching to fail.
The LE to strut connection is internal and is hard to detect leaks from, and can also be difficult to work on, because you cannot see if the teflon tape has sealed the connection properly.
Kites generally fly nice, one pump system is not so nice.
