Whilst i was looking for a new surfboard the other day i saw a new form of fins that are being made. They're called the skater slater fins . They are a set of 4 set like a twin fin one behind the other, has anybody else seen or tried these. The bords that are using them aren't as wide as the twinnie, they are more like the 181/4"-181/2" that i'm riding. They give you drive off the bottom but the missing back fin allows you to slide the tail around at the top. Obviously not so good at reef breaks but coukd be sweet at the local beach. Has anybody checked out the surfing posters site at Hunuwan. It has a great section on choosing a surfboard and more advanced design?
