It may depend on your fins too. Avanti Quattros (and the newer models) are good, Sherwood Magnums are really good (although I didn't like them much going forward). Cressi Garas are excellent (but why are you wearing them for a dive in tight spots in the first place). Sometimes I wish when they did fin reviews they put this stuff in. I don't really care how much more efficiently they push me through the water, I want to know how much control I have!! Can anyone out there swim backwards with split fins?
