Finis Foil Monofin

Anyone here own one? I was thinking about getting one of these as both my girlfriend and I are starting to pay attention to our underwater dolphin work more. Did you find it helpful? Gimmicky? Pros..Cons? Thanks! Have you been dolphin kicking a lot with long blade fins already? I like the fibergalss Finis Shooter better than the Finis Foil. To me, the rubber one is not too much different than fins and too floppy. But the Shooter can be harder on the joints at first.
