Search! This has been covered countless times. I like my Force Fin Excellerator model, but they are stiffer and feel more like a traditional fin than the regular Force Fins. Not too fond of the original Force Fins, although I have an old pair. The Excellerator has plenty of power and comfort. With my feet I like the open toe foot pocket and the fact the blades are narrower than regular Force Fins. The kick takes some adjustment, but it is a personal decision. You gotta try them out to decide. They feel like you are not wearing fins, (although the Excellerator is an exception to some degree) but you get around pretty well once you get the technique. Then again some people hate them. I have had jet fins, other split fins and these are my favorite now, although I want to try that new Mor-Fin that got a high rating in Scuba Diving Magazine's test. The Mor-Fin manufacturer is only about 30 miles from me, so I may try to get him to loan me some to test if I pick them up.
