I've been riding a 14M Spitfire and a 132cm Redline for about 6 months now. Been out about 100 times on this gear if not more.
I can't say enough great things about the gear. The kite has been spanked, twisted and rolled about 100 times in waves. The board has landed on the sand bar or beach with some close calls I've had. So far no damage other than normal wear.
A++ durability, air time and steering is insane. Relaunching is easy in 14 knots and above for the 14M - the 10M is much easier to relaunch (I use that in 19-27 knots).
I have some videos posted with me riding the 14M and the 132 Redline at about 16-19 knots: (my weight is about 140 pounds)
I have heard people say this board is "slow", you won't agree when you see the videos.
