Boogie711:Second vote for ScubaPro Jets (Aqualung Rockets are not the same.) I also own a pair of Mares Quattros. And if you have anything larger than a size 11 foot and a big boot (as in, a dry suit boot) you'll want an IDI Turtle, or the new XXL Scubapro Jet... the old Jet's had ridiculously small foot pockets.
Split fins are a tax on the gullible... they may give you OK straight line thrust, but you can't maneuver in them and scores of divers have reported they're useless in a current. Your dive shop is pushing them on you because they're also expensive as heck.
I find myself in complete agreement with everything that Boogie has said.
I have ScubaPro jetfins. NOT split fins.
These are nice, short fins, very sturdy, that give you satisfactory thrust as well as being small enough to fit into your carry-on luggage for scuba travel. Anything larger would need to go into your check-in baggage. Check-in baggage can get lost. Carry-on never gets lost, unless the plane goes down with you on it as well.
If you have a major issue with swimming against currents, such as in the U.S. northwest, then possibly a longer fin like a quattro would be appropriate. Other than that, the smaller, firmer ScubaPro jetfins should meet all of your needs.
Split fins are a farce. I think scuba stores are trying to unload them. If they truly have an application, it is for weak divers who have never done any athletics in their lives, and who cramp easily in the water. They are a crutch.
Turtle fins are similar to Scubapro jetfins, although I have never used Turtlefins myself. I would recommend a short, firm fin like the ScubaPro jetfins or the Turtle fins, rather than the long quattros and their kind.
Make sure you try on the fins before you buy them, over a dive boot, preferably the boot you will be wearing when you dive.
