I met my brother today at a funeral, haven't seen him for many years.
I gave him a crappy old board may years ago and it had a star fin in it so I asked him if he still had the board and more importantly, did it still have the fin in it.
He did and it does.
So he's going to take it out and drop if off at mums place one day so I can pick it up.
I think I'll give it a go in the 10' miske model, should be interesting.
