I am looking into buying Captain Nemo Powerfins for deepish freediving. They seem to have a good blade, are durable and not too expensive. I used to dive with a Mono fin, but my back can't take it any more. I like soft fins, but want them to be able to carry me up from 50+ in a 7 mm suit and 5 kg weight.
What are your experience with these fins for deeper diving and what kind of stiffness do you recommend?
