So you are changing to a different kite and brand I assume because of an absent patch.
Even tough he personally has never had a issue.....with said patch.....only that the kite designers ideas about the kite they designed, need corrections....or that he needs a patch so badly that cutting one out of a single euro worth of kite repair tape, and sticking it on is to costly, or labor intensive.
Double Right O.....
I suspect we are having a language/ translation, issue. If a beer can diameter patch, coming and going as the values changed from 2013 to 2014 is too tech to understand, then I am confused...old valve, and patch, for a few years then gone, new valve that has jagged edges, and a large plastic screw, and the patch is back....Seems simple to understand....
Good luck with what every kite you choose in 2015! I hope you find the perfect one !
