Funny I though the same thing. I want to try and kitesurf my V3 with surf board fins. With the thruster set up they are okay, but too fast down the line and hard to break the fins. be better if I had a drifting no brainer kite. VX too fast already i the surf cross shore, add a sector in! On shore had a couple of good sessions in the waves on the sector, but all very controlled nothing to write home about, but not designed for that. Love the fact I can still do all my rolls, transitions with loops though on it! Yeh if I can get some SB fins in, I might give it a go in the surf and then on a kite.
I'll report back after my trip to Fiji next week
