some quads lend themselves to push-pull (Spirit and TC Ultras) as opposed to wrist rotation, (Revolution derivatives)
Some are best at no wind vs. beach gusting
no kite enjoys turbulent air
some fliers like short string lengths and some go long
"take the best, dump the rest"... = Everyone will offer advice, take their best stuff, make it your own, anything that doesn't fit you perfectly discard, repeat until you have your own unique style, visually recognizable, not by the kites you fly, NO by the way you fly kites!
Enjoy the journey and your best investment is still a road trip (to meet up with others, you want to learn & they want to share)
I have about 60 quads in all different styles and configurations, but the first one was a "Backtracker", followed by two Rev2s used from the Kiteloft, then a vented and a SUL 1.5 (it rained the day of delivery). My favorite kite is probably the Zen, I have owned four of them. Each was repaired repeatedly by Master surgeon before funeral rites were offered up.
I am a big fan of Eliot Shook and Bazz Poulter as kite builders. They will do exactly what you've paid for, regardless if that means deviating from the approved standard or trying something kooky out. (SUL leading edge sleeve on high wind vented kites, covers over knots, extra reinforcing patches, custom materials)
What I like, you very well may not, choices are good enough for everyone to share the sky and enjoy each others company.
