Hi
can anybody tell me the difference between two different fin position on spleene door
1. larger two fins (5 cm) are on the outside of the board, smaller (4cm) inside
2. smaller outside of the board - on the edge, larger inside

which position is better for upwind, and which for agility

thank you

I want to know too.

I use only a middle fin, no edge fin. This makes the board faster, easier to turn, more fun, plus it reduces face spray/

I tell this to everyone I know who has a Door - once they have tried it they love it. You can try it with either the large or small fin and decide for yourself

I want to know too.

5mm Fins in the center, the smaller fin on the edge.

I'm on my 3rd door (now riding the 159) I prefer just the 4cm fins on the edge i cover the extra holes with clear packing tape if you clean the board first the 3M packing tape stays on forever (don't like middle fins only at all)

I find this makes the board much faster and a bit looser.

which position of fins is better for upwind in really low wind?
which position of fins for high winds?

don't know what is best for upwind, but know that big fin must be in center of board, because board much fatter in this place
