FCS II H4 Fins

Q: Ad says thruster, pics show quad. What configuration are you selling?

If it says tri fin set at $150+ its a thruster set. If it says rear quad fins for $90ish, thats just the back fins. In order to get the quad set, you need to first by the thruster set. Total investment about $250. And well worth it. Its the only fins i ride now, 2 foot mush to tripple overhead.

Q: What set up is this? Quad or Thruster?

You are either buying a thruster set up ($150-$175) or buying the trailers to make a quad set up ($90). I recommend both, so you can switch it up, if you have the board set up for it. Best fins on the market so far in the FCS family.

Q: Would using these h4 quad rears with some standard side fins like kolohes feel weird? do they need h4 side fins to unlock their magic?

You would probably feel a little difference by changing only the 2 back fins. But I honestly love this fins. I live in hawaii and been surfing for over 25 years. I’ve tried a ton of different over the years. Most were the best fins available at the time. But hands down these fins are amazing, probably the best I’ve ever used.

Q: It's large or medium these fins

if your weight more than 70 Kg then you need Medium size i already bought M
