Hey there BBeall, first of all, I will agree with Peter Guy, the Mares (correct spelling) Power Plana's are the way to go. Disclaimer, yes I use them, and yes I sale them. But with that being said, out of your list, I have used 3 of the fins listed. The Hollis F1 / F2 and the Scuba Pro Jet Fins. I would say, keeping on topic to your question of the ones listed, I prefer the Hollis F1's. I have used them for several years. Down side is they are extremely heavy. So fin kick pattern makes a difference. An individual's body type / athletic ability makes a difference too, when using heavier fins (not to mention the type of diving you do, be it drysuit diving, tech diving, drift diving, public safety diving, or even salvage diving). In your area, my suggestion would be ask some local divers, or even you local dive shop, to see if you can rent or borrow a pair and see how you like them before you make a purchase. Diving is much like any other sport (I will use shooting sports to make the point), most shooters over time collect many holsters that come obsolete, or does not meet the criteria they are looking for. So they have a whole drawer full of them. In diving, the same goes with gear (fins). If you stay in this sport long enough, you will have a closet full of fins. It’s always good to try before you buy if possible. Ask around you may be surprised at how many local divers will let you borrow or demo gear. As far as your trim goes (not being able to lift your legs to fix trim), I would suggest changing your trim with your weights (relocating the weights be it hard or soft), such as what you would learn in a Buoyancy class or even a Sidemount class. You would also be surprised at how much difference it makes putting weights on tank cam straps or even in other areas (clip on weights on shoulder D-rings or even zip tied to should straps). Hope this helps.
One last thing, the Mares X-streme fins, are extremely light weight and very powerful, if the diver does not over kick them. They do tend to be slightly difficult to frog kick with, but with a little practice, it can be mastered. If you were near Taylorsville, NC, I would be more than happy to let you try all 3 (Mares Power Plana, Mares X-streams, and Hollis F1's). But definitely check with local divers in your area and see if they will let you try what they have.
