tks bnthere, I dont ride naish so I wasnt sure about that one. So to summarize,
for 4 line kites as of 2012
Y-mini-5th line quick release: cabrinha, best, north, airush, epic, switch, gk, core, ocean rodeo
single center line flag out: ozone, slingshot, liquid force, wainman, blade, naish
I don't want to comment on older kite control bars because it would take a spreadsheet to get all the details right.
Bille if you have single center line flag out if you don't want the bar to shoot all the way up put one of these
With a short piece of line figure 8 knotted and then larks headed and lock stitched 10 meters up on your line. It will stop the bar and if you attach it correctly won't decrease line strength. This is what ozone uses on their flag out line.
