I have been diving for 10+ years using my Oceanic Vipers. I purchased the Seawing Nova but found them too stiff and fatigued my legs; I had to return them. As I research a replacement I have narrowed down to these 3 fins. Given that they are all Mares - my question is what are the tradeoffs between the 3. I generally do wetsuit diving in the Caribbean and Southern Pacific - wetsuit only between 3mm and 7mm with some currents [Komodo is in the future].
