Interesting to hear about your experience with the 707. Today I had the best windfoil session of my life. So good that I almost think I might never windsurf again.
I was on the 808 with the 370 stabilizer and had amazing rides in wind swell. I used my 3.3 sail, which really is the key to good wave windfoiling with a small sail.
Great speed, solid turning, and some epic hits off the lip (goiter, kono).
I also tried the Reverse 375 stabilizer, but I didn’t like it. It felt slow to get into flight mode, and the board didn’t fly evenly, I had to shift my weight back too much. So that stab is going up for sale :)
After that I tried the 325 stabilizer, and wow, that’s a really good combo with the 808. I’m now thinking of buying the 93 cm mast, because I believe it will give me even more of everything.
