Well I read the Rodales article on fins as well. I use Apollo bio fins normally (Puget Sound codl water diving with boots) but wanted to try a warm water / snorkle fin.
Had a heck of a time getting the Caribe fin. No one locally (WA) carried the fin that I could find. Finally ordered two sets (one set for my wife and one for me) out of Mike Parnell's shop in Chicago. Great dive shop to deal with by the way.
Anyway, took the fins for a test in Florida. My wife and I really liked our Caribe fins. They were just what we wanted for shallow diving, photography and snorkling. Harder to get off getting into the boat and the ladder was rough on bare feel but all in all, worth the money ~ $40.00
I disagree with the ratings on power. My apollo bio fins perform much better for me in current and when I needed power to go. So now I am stuck with carrying both fins, luckily the caribe's are very light and pack nicely over the Apollo's in the dive bag.
BTW they look way cool in the water. The flex of the fin with the up and downstroke is very .... artistic????
