I learned to frog kick in my old aqualung blades. Not the blades II, those are junk. Having tried jets, Hollis F1's, F2's, Mares quattro's, eddy's, turtles, HOG tech fins, and basic paddle fins by Aeris, Tusa, Genesis, and Edge, as well as Atomic splits, and some generics I've found that the basic frog kick can be done in any fin. If the base technique is solid, the fin doesn't matter. I frog kick in my 3 ft long MAKO free dive fins and they work just fine. You just need to adjust the base technique for some of them and use less power, more power, more finesse, etc. and just relax.
It's a very relaxing kick that many people I've worked with got once they stopped trying to overpower it. That is also a big mistake I see when teaching people to back kick. Which again, once you have the base technique down, can be done with any fin or no fins. I can back kick much faster with no fins and just boots on than I can swim with just wetsuit boots.
The frogkick is not a constant kick like a flutter/scissor. It's a kick and glide technique. Can you do constant? Sure. But when I do that most of my buddies have a hard time keeping up. Plus, it's not a race.
Right now I use the HOG fins for 95% of my diving. For big open water like the Great Lakes or open ocean, if I'm not doing penetrations, I'll take my F1's.
