Great advice from Remi & Jeam-Marc. The iS80/W49 sounds like a good option. Or, If your sailing in proper speed conditions, then W44/W53 would be best. If you want just one board and you have just small chop, go with W54, but get two fins, one small speed fin (25cm wide base/23cm Assy etc) for perfect flat days and a second more control fin for chop (Tectonic F1 Falcon 28cm).

The 1st generation wide base fins are doing very well now. I switched from normal speed fins (Assymetricals, raked etc) to Tectonic Nomads (also tried C3 Slingshots) and I love them. Regular speed fins have great top speed potential, but they also have a very narrow sweet spot to be be in the 100% range. This means you need at least 3 or 4 (or more) fins per board to be at top speed all the time. No good in gusty locations, as super tuned fins can not cope well here.

Wide base fins are 95% as fast as specialist speed fins but they have a massive sweet spot range, so you do not need so many fins. They are fast on tight courses as well as super broad courses (110_150 degrees), also good enough to get back to the top of the course and pretty good through rolling chop at the bottom of the course.

Since I switched to wide bases, my PB's keep going up. recently got half an ants testical shy of 44 knots in not great conditions on a Tectonic Nomad 21cm. I am normal speed sailor, and wide base fins are made for normal speed sailors to go super fast, easily, in big range, on all angles, in most conditions (even in not good conditions) and to be safe (spin-out free).

You have a great choice of wide base fins, Vector, Tectonic (my favourit), Sonntag fins, Curtis, C3

You can probably tell I really like
