The problem with FF Pros, since I actually have some, is that you really cannot perform the full range of kicks with them compared to the Jet or Avanti. FF Pros will not frog kick at all, they don't back up well either but they are an efficient fin for a flutter kick, just lack maneuverability compared to more conventional paddle fins.
I bought my FF Pros back in about 94. I used them quite a bit and recently eBaited them. I simply could not use them efficiently for photography, with my Jets or my Avanti, I can lock myself in the water, with the floppy split fins or FF Pros, no way, simply no precision with them, the blade folds under to easily which is why I cannot "lock" myself stationary like I can with Jets/Avanti etc.
