The Dive Rites sound good.
This is what I liked about the Mares. Probably the most important thing is that I am use to it (been diving it for years). I 'feel' like it creates a lot of power but a lot of that might be mental (I can picture the fin folding up and moving the water when i think about how it is designed and so it gives me confidence). I don't like that they sink but I feel like I have my trim down pretty good right now. I am not sure how much a change in fin would effect things but I struggled to get out of being tail heavy for awhile.
I took the rocket fins back-they were just so heavy. I'll have to consider some of these others as well now. I just need something for warm water diving, something that I could take the fundamentals class with and something that gives me power when I need it, honestly, I usually kick in a very slow manner. I am not racing when I get under water but I do dive in the ocean so sometimes I have to deal with current.
