On big days like those approaching in the next couple of days, I switch fins. Imo, large scuba fins WORK and take less effort than small bb fins, plus you save your arms the wear and tear. Obviously this isn't for dk, I only ride prone. Anyway it may sound foolish but the thrust generated from larger fins is a huge plus in huge surf. Saved my ass countless times.
Totally agree. I use big fins after buying a pair of small bodyboard fins. NO COMPARISON. Snorkeling fins are way better and give much better thrust. Unless you ride dk, no reason to use short fins. Twice the work with 1/2 as much trust with short fins on a long paddle out into the lineup. You do have to get used to the big fins though. Different technique required.
