Got out on the new Black Project S-type 29cm fin yesterday for quick shakedown test. Crappy east wind up and down and shifting direction. Water very choppy with no swell to flatten it. Used 7.3. Got a 35.3 peak and a 35.0 100m out of it on not a particularly clean run. That beats my previous best 100m on the 7.3 of 34.8 knots which was done in competition in better conditions and I was trying harder! No sign of laminar bubbles, very stable, did not spin out once.  Definitely faster!
