the ForceFin outperform the Jets in every kick except the frog kick. They have a completely different feel because you are going from a very rigid fin to a very flexible fin, but once you get used to them you'll find yourself moving easier and conserving air, just have to give yourself 4-5 dives to get used to the different feel and you'll probably be hooked. If you really need a good Frog Kick the Excellerators are the fin for you.
