The concept of the separation is similar but I think the SP system is cleaner and can be used with a small screwdriver if you don’t have the tool handy, probably more evolutionary than revolutionary.Read through this whole thread, lots of great information, but I have a few questions & comments.
The separation aspect looks like a direct copycat of Tusa's Hyflex Switch / Switch Pro fins. Not that that's bad, but worth remembering they weren't first. I found the Switch far too soft for my liking, and haven't had a chance to try the stiffer Switch Pro fins.
I found the Seawing Nova fins also too soft for my liking, but the Nova Gorillas have really hit a sweet spot for me. Like them more than my Mares Avanti Quatro+ fins (lighter too).
What I am really curious about is: how do the Supernovas compare to the Nova Gorillas?
Will there be / is there a Gorilla/stiffer version of the Supernovas?
performance is more like the gorilla than the regular nova but more stability in the blade action, so far I’ve only used them in cold heavy drysuit waters and they did very well, I will be using them a lot to see if they break.
