Where I flat water paddle it has a side on wave all the way for about a km.
if you think of it like a centre board on a windsurfing board ,the bigger fin is always going to be more stable
in those conditions ,but as DJ ,said DWing it will be fantastic .
great to have a choice now Dave

.
sometimes I will go in and change fins .if not to far away .if not happy .
time will tell.
