I tend to agree with G salt first couple of comments.
It may not seem like much area ,,,,,, if you extended the swallow into a pintail. BUT IT IS .... supprisingly enough as you push off on your top turn you LL have less volume / AREA behind your fin and stap on your tail which will give u more release and potential slide as apose to a solid pin which will want to hold all the way through your turn.
Anyway what sounds better 8 foot 1 OR 7 Foot 11 ???

As long as it fits into the ute ............she be right

Ps werent swallow tails designed so the didnt fall out of the retails racks
