Aren’t some of the listed fins, including the split fins, poor fins for the frog kick fin, in performance and feel? If I’m wrong, please tell me why.
My training performance preference would be the frog kick over the flutter, as about 75% of my typical training time is with the frog kick/breath stroke.
My Atomic splits are very stiff. I do a mile at a time in the pool, which is almost all flutter. If I’m practicing frog, I’ll switch to my Deep6 Eddy fins I actually dive with.
