yeah. I own 390's and Auto Evers. the auto evers are WAY lighter. but they're way more stiff than the 390.s I think they are great bindings. super comfortable. very adjustable. the only drawback is that they do feel kind of heavy.
nah my flow NXT FSs are lighter then 390s lol...union contacts are wayyyy lighter then 390s, im not sure but i think nitro zeros are pretty light too. not saying 390s are a bad binding, or if its even possible to distinguish the weight difference between the 390s and contacts.
they're actually heavier than my T9s
the heel strap is fairly dense, and the heelcup is anchored at the toe edge
