I bought a pair of medium length fins in December and I still don't know what I think of them. I worry that they are easier than zoomers (because I get more propulsion) and easier than long fins (because I can kick with a faster tempo). But maybe I'm just imagining all of that. As others said, you really have to work them; if you're kick-oriented like me that requires an extra effort not to slough off.
