I think efficiency discussions focussed on getting in the water two or four minutes faster are misguided.
If we want to talk about efficiency or speed lets talk about the back end & packing up.
You will end up with a nice compact kite in about 30-45 seconds
1- hit dump valve
2- line up kite on ground with the wind
3- un-clip the 5 struts
4- lines stay attached w/loose amount of lines in kite, bar/lines 2 feet in front of central LE on board
5- roll wingtips to center.....fold in 3...put bar lines on top of kite...ready for next time...bar is clean
Time : 1 min. 15 sec. for a XR3 19 and i did not spend any time disconnecting lines off the kite
Safety : perfect compact pack up every time for safest super fast launch next time out
Efficiency and safety..............no misguiding
