I haven't ridden a single fin since I was a kid. Can anybody recommend an appropriate fin for it? Cheers

Perfet Fin would be the NPJ Wolfhound by the Salty Merchant.
Got one in a 6'6 rounded pin single'o.

You would think a single fin would be easy to sort out on a board,after all its only one fin.
I have never had so much trial and error on any board I have owned till got a few single fins. The wolfhound I don't really like that much,but the aura which is a bigger but more of a thinned out tip I really like. Both fins were used on my 604. I find the aura give me a bit more flex and feels way better on bottom and top turns. I should give the other more of a shot,but it becomes one of those,I don't want to waste waves scenarios.

I would be interested to know how you go and what you like about it

haha yep single fin is so precise gotta get that back foot in the sweet spot. When you do .....
