I haven't flown any of the new Naish kites. As a truism, you can expect some variability in relaunching technique, ease of relaunching from one kite to the next. Some kites almost relaunch themselves automatically in enough wind, (like it or not), while others take some coaxing to get back in the air. I think Rush might have some time on the new Naish kites.
