great topic,..very interested to see what techniques are being used specific to the roll over bridle design,..
My main kite spots feature very limited beach widths at bad wind angles with lots of obstacles (beach debris like large boulders, tree branches and logs). I still use the old technique of folding over one wing tip and weighting it with big pile of heavy gravel or sand.(its a good idea to leash your kite off while your setting up the kite,..perhaps to heavy log,..you dont want it taking off while you heading back to your bar).
I walk back quickly to my bar after weighting the kite and connect my leash and then hook into the chicken loop,..I really keep a constant eye on my kite during all this.
I slowly walk back powering up the kite,..if all looks good I “pop” the sand of the wing tip and fly the kite up. You have to make sure all your bridals are free and clear before initiating lift off. Because of bad angles at my local spots,..these launches can be quite “hot”,..you want lots of throw (sheeting range) on your bar for de-power as the kite surges to the edge of the window. Also,...I always self launch away from the beach goers in case I have an issue with the kite.
If the launch goes wrong,..,my first action is to just let go of the bar ( I use a free-ride bar with no stopper due to the sketchy launches and landing we have deal with). By letting go of the bar, the de-power bridals give me max power via the roll over action - this is the same de-power you would get releasing the chicken loop and going to your leash.
