Hi there, I've picked up a pair of Scubapro Twin Jet fins...but all of a sudden all I see are reviews for the Twin Jet Max fins and those reviews are stellar. I'm going to be going on the occasional warm water snorkeling trips for now...and I'm on the fence between returning the twin jets I have (never used them) in favor of the twin jet max if only because of the re iews I've seen. ARE they really that different?
