The V-6 is also a good fin according to test results. I haven't used them personally so when I say the fin is probably the best choice for an all around resort fin, it is according to advertising and reports. You could do a lot worse. My experience with slipper fins is in the context of spearfishing starting from way back but notably, in 1979, with the Cressi black rubber long fins. Lately, I have been using the Mares Avante Tre which is a predecessor to the Superchannel. I can't tell any difference between the two when compared and tests are virtually identical. IMO, these two models are superior to the early long fins and some contemporary types but it is hard to find data on long fins and I'm not in a position to compare all of them. What I am saying is that serious free divers should look closely at the Mares fin, especially those diving 60 fsw or less. Otherwise, it would be hard to go wrong with the Caribe or V-6 which are fast and maneuverable. For carry on purposes, the Caribe and V-6 are probably the lightest in weight. The range of prices is not overly broad so no decisive edge there. Comfort of the Mares Superchannel and Oceanic Caribe X are outstanding, really smooth and well fitting for normal feet with no constrictions on the toes. I haven't tried the V-6 so somebody else can speak to that but Oceanic makes it so that is a good sign.
