Might be more about the different beaches than fin placement I have the same board/fin in LA riding mostly inconsistent beach breaks and occasionally points. No issues so far with the middle placement.
Side note - The worn out fin comment was really interesting. Didn't know that existed either.
Looking for a board for a trip down to Central America. Not set on size or shaper, just want a single fin for a point break for shoulder to head high waves.
If you have something you're trying to sell, let me know! Just needs to be under 7'6 to fit on the plane.
