Anyway, they say plastic rides the same for a few months, then they loose spring.
Nope, they'll definitely still cut you. Been there done that. Also a rounded edge on the back of the fin is not going to make them any safer when you have speed and weight pressing you onto the fin. They'll just be slower
Plastic = flexy. It's easy enough to just test them in your hands. Go to your
local surf or kite shop and buy at least some honeycomb or fiberglass fins.
Love the Stretch Quads on MPH boards for quads, the AM's or F4's Blacksticks for Thrusters. Most of the time I'd rather kite with the thruster setup especially on mph boards.
Own 2 vanguards, a nano, and a ridden the Vader a TON.
