After a couple of minor injuries from my Reflex boot hitting my hind leg, I've been thinking about changing my setup (Reflex with R-style rear). Anyone out there on the Fluid Motion EVOs? I like the simplicity, but am a little concerned about the release and durability of the cuffs. Also, their Quattros seemed really heavy. And the boots seem wide, based on trying my brother's that is way too short for me. Advice?
