I'm just finishing shaping a 5'10" egg to surf at my local when it's gutless (usually). It's pretty full figured but I'm trying to squeeze some performance out of it with the rails and the bottom. I surf twinnies 80% of the time but would like a little extra drive for this board. So I'd like to experiment with a three fin set up that I could surf as a twin + trailer and a traditional thruster.
Should I just place the fin boxes as a typical thruster set up or are there some other consideration?
