Hi,

I had been using my Dyno 95 and Blade 4.7 for a while, using a Blackproject Kraken 28cm fsw single fin at the beginning. But I had been spinning out frequently when i land from a chop or when i try to go upwind, olso i feel it is a little difficult to go upwind. I am still trying to adapt my stance to weight my front foot but can't do it on gusts or over heavy chop. Severne recommendation is a f320 (32cm freeride) fin, but i was told to chose 26cm or 28cm if i want to be extra safe by black project.

I am an intermediate sailor and i am not having any spinouts with fox 105 (standard f360 fin) and 6.5 gator and i can go upwind easily.
I was wondering if my fin is not suitable, or my technique is not there yet for fsw boards.

I never tried the standard thruster fins before because i was told multi fins are for waves and single fin is better for freeride bump and jump. There are no waves to ride here, just open Mediterranean sea waves and chop.

Frustrated of spinouts i tried the supplied thruster fins (20/12,5) for several sessions with 5.5 and 4.7 sails. Board was harder to get into plane and speed was olso lower, but the ride become much softer and controllable over chop or at gusts, it almost felt like wind dropped 5kts, no more spinouts just occasional small slides if i push hard on back foot, easier to get upwind as well but still harder than fox 105. I wish i tried it earlier.
Comfort and control is more important for me at harsh conditions so i plan to use this setup but i am still not sure if using a better single fin will make it even better.
Any advice on this subject?

Another thing i was wondering is sometimes i hear a noise from fins, same noise if some weed is stuck on fin, slows me down, but when i jump in and check, no weed. Is it possible to hear that noise if one of the fins have air bubble and rest doesn't so i can keep the direction?

Cheers
