as a small, short female, i am pretty happy with this fin. it is pretty light, not-too-long blade (so easier to handle, especially above water), even though the foot pocket is still too wide but the buckle allow me to secure my feet deep into the pocket, and produce good enough power. i like the buckle a lot as i've found it very easy to tighten up before diving and to unclip after diving. it is more eficient with slow & long kicks than fast & short kicks.
cons: this fin seems pretty useless for froggy kicks and backward kicks.
this fin has brought me to safety against horizontal, up, down, and washing machine currents in some occassions without making me hyperventilated or god forbid, panic. good enough for racing along a whale shark, even tho i dont think it will propel you to be a winner
