I now dive with the new Scubapro twin jet max fins, and I also had dived with my (classic black) jets for years, and I'll say the new fins DO perform as well as the jets. Now, before I'm drawn under the ship's keel hear me out. Compared to the Jets, the twin jet max have a great edge in speed, not that it's important for rec diving, but as an instructor, it's easier to pursue and overtake an errant student. I can do helicopter turns, (oh yes) reverse kicks, modified flutter and frog kicks. I do feel the jets do edge the max over the frog, not much of a difference in the real world. As for diving in current like the Duane wreck here off Key Largo, both are tied. Seems like Scubapro really did a nice job with the new fins. The only qualm is that I can't seem to find spring straps for them as Scubapro doesn't make them, for that the jets have an great edge.
