Thanks Fondueset! I've decided this is going to be the year of the monofin for me and right now, it seems like either the Dolfin or perhaps the Lunocet (depending on how the reviews shake out) may be the way to go. Knowing that you've had a good experience with it. . . especially in relation to the Starfin and in cold water to boot is very reassuring that I'm not barking up the wrong tree. As it currently stands, my biggest concern with the Dolfin really has to do with portability. It seems like it could be quite a thing to pack on trips (not that a standard mono would be much easier). . . though perhaps I'll just stick to using bi-fins on vacations. Thanks again for all the information!
