I'll jump in in case it helps put a different perspective on your selection. I started off with little/short stiff fins until I went with Omers Plastic long fins in 2000. They worked fine but I had issues with blisters. Then. I tried a couple of different plastic fins in various foot pockets but they were just OK. The stiffer fins put a lot of stress on my Knees.
Someone I repect told me to try the Moana's Hybrids in Pathos foot pockets and they are the best most comfortable fins I have ever used. I can swim all day in them with ease and doesn't put pressure on these old worn out knees. I did the heat treatment on the Pathos Pockets and they are very comfortable. I know Dan used to carry tem and thinks they are bad pockets - but for me, an old guy with worn out knees, the Moana's Hybrids with Pathos Foot Pickets are very easy on me and very comfortable.
Caveat: I no longer dive 100 feet or push myself but I personally know many deep hard divers that use and swear by the Moana's Hybrids in Pathos Foot Pockets. The hybrids are said to be medium tapering to soft on the tips. Not sure were they fit in - but feel softer and easier than most plastic fins I tried.
