Actually, what is the point of having one kite quiver?
Yes, everybody can have one kite quiver if you are not demanding to much. If you are out only few times in a year, I guess that one kite is pretty much enough.
But if you want to develop, be sprtive, be out in high and low wind, take waves and flatt water, but go out also in choppy water, you cant even dream to have one kite set. with one kite it's always compromise.
If you want to get the most out of kiteboarding you have to go few kite /few board quiver.
I don't have one trouser / shirt closet either..
