Over the 10 or so years of my kite flying, I have done 3 "perfect" tricks.
They have all been with old school low wind kites and on a single pull.
They have all looked as if being done in slow motion.
1) Taz Machine on an Inner Space
2) Double Slot Machine on a Mojo UL
3) 900° to a 2-point landing on a borrowed Synchro SUL
In each case, the kite would flatten out quickly and then spin slowly while I walked forward to maintain slack.
There is this thought that a kite must have enough mass to do a trick from a single input, which seems to rule out the ability to do double spins on kites weighing under 7 ounces or so.
Still can't comete, although I'm getting closer. Until then, I'll continue to enjoy what "old dogs" can do with their short standoffs and curved leading edges.
Of course, I'm an old dog too.
