What are the differences and/or advantages between one size or the other, apart from the size obviously? I was under the impression that all Futures longboard fins have the same base size for fitment into any Futures longboard fin box but don’t get why the boxes are available in two sizes.
I initialy thought that maybe as with some longboard boxes, it’s possible to slide the fin forwards or backwards with the larger box but I can’t tell, can’t find anything on the www which explicitly describes the difference between the two.
Cheers :-)
