Force Fins, Force Fins, Force Fins, Force Fins. Almost zero resistance on the recovery stroke, tons of power on the push. They are pricey, but they are well worth it. I got lucky and picked up a pair at 1/2 off for $50. They are the older style and are only adjustable at the heel. I've used many different fins over the years for many different applications, Force Fins are the best all around fin I've ever used. I was told it would take a trip for every year I'd used regular fins to get used to them. The salesmen was a little short though. They feel so easy, that it's like your not pushing all that hard, so you think you're going slow. Then you see your friends are left behind, then you begin to see just how efficent these fins are. Knowing how good they are, if I ever have to get new ones I'd pay $200+. Given a choice, I'd never use another fin.
