The Sea Wing Novas flop a lot on the hinge, which allows recoil and therefore gives you a low energy expenditure to thrust ratio. Meaning you can go "fast" without feeling the pain. Having said that, if you have the leg strength, you can burst much faster with Jet fins than with Sea Wing Novas. Even on a nice cruising speed, Jet fins will beat out Novas, provided each diver flutter kicks effectively for the fin they wear. The Novas have a top speed that is much lower than the Jet fins, however it is easier to maintain that top speed; relatively speaking.
The big downside to Jet fins of course is whether you can maintain a cruising speed or not. I've been diving them for two years now, and make a 900yd swim in just under 18mins. Friends with the Sea Wing Nova's and split fins usually do much much better.
I can attest for a fact, that if there's a heavy surf break with a powerful suction, friends who have had the Sea wing Novas were not able to break through out of the surf zone and into the beach. They had to wait until a wave pushed them onto the beach, where they could dig in and crawl out.
In fact, the only people who could break through in those conditions were those sporting stiff fins, this isn't to say everyone with the stiff fins were able to though. Examples would be Mares Avanti Quatros, Jet fins, and OMS Slipstreams, from my experiences. There are plenty others as well that would also do that job.
Overall I think you should get the Jet fins and just train yourself up. Unless you have weak joints in your legs, you will be able to adapt to them with little time, as long as you don't take long hiatuses between diving or swimming with fins.
