it's also not just how the kite gives you time to hook back in, when you pop hard with your kite low it gives you a ton of slack to make it easier for handlepasses. they also give you the most explosive pop , though some SLEs come close
the funny thing is the "disadvantages" of a C are what makes it so good for unhooking. the shape gives it worse overall windrange but better useable windrange. i can unhook on my c almost through the entire range of the kite (once you have enough power to pop) whereas a bow or sle is much more sensitive to trimming so you get less useable unhooked range. you also dont get the stupid surge of power when you unhook either, its more consistent to load up against and you get slack like a cable. again, some sle's come close but still nothing is a C kite.
it just depends on which sacrifices you want to make, do you want performance or ease of use. some modern c kites are very high performance but are still quite easy to use and wont kill you trying to learn tricks. i am currently riding the mutiny p-series and have progressed more in a few weeks than i did in months of owning bow kites... never going back
Yes agree on the pop. Not that I do much unhooking, but I know what you say and agree...except there are bridled kites that easily merge the gap that used to be there.
