I have a set of Atomic split fins and they do nicely for recreational dives with little to moderate current. If you plan to dive in any overhead environment and need to scull or plan to dive in medium to heavy ocean currents, I would avoid them.Atomic splits are nice...called smoke on the water, firm enough to allow a frog kick, and very smooth...might want to try Hogs, as they are similar to turtles but give me (don't know about yourself) nice control for less money.

anzac65:Oh, so are you suggesting that for some reason a fin stops working because it's being used in a body of water that's moving rather than stationary ?
I'm not speaking for bsumner, but I think we all know than any pair of fins will provide a finite amount of thrust. When we dive against a current, part of that thrust is needed to just stay in the same place, any extra thrust lets us move against that current. As the current increases, there is a point at which we can no longer make progress against that current and shortly after a point where we can no longer even stay in the same place. We will reach this point regardless of which fin we use, although that point may be reached at different current speed with different fins. I suspect bsumner is telling us that point is reached fairly soon with the Bios. I've tried Bios, but never in a strong current. I have tried Twin Jets in a strong current and could make no progress in a current that I know I could have moved fairly easily with my Jets.
