The better rider crashes their kite a fair bit more often, as they try to do tricks.
So you need a more reliable relaunch, from any weird position, in any wind.
You also require a certain amount of pull during a kite loop trick and when riding unhooked.
Kites with bridals have great relaunch.. in Adverts...
With bridals in real wind, your flucked, mate no where near enough control in the water.
5lines lets you manipulate the kite while its in the water.
Bridals pullies tangles inversions you have NO control.
Camsand buy a Wipika Matrix (or a Vegas) they have soft bar pressure (preserve your strength for a trick) plenty safety and enough windrange too.
