The Raiden's really look like a solid binding, simple like Union, but maybe a little more tech. Raiden's just look lighter, but I know that means nothing and could be lead wieghts. The thing that has me looking at Raiden's is the adjustable heel, Flux were on my list too, DMCC and SF45, but the Raiden's just look solid with less parts to fail.
i saw a pair of raidens on sale for 70 so i grabbed em'. liking them so far the only issue ive had is the center plate has weirdly shaped indents for the bolts so that they can wiggle around a tiny little bit. doesnt affect anything, but just thought id say. i dont have the phantoms specifically but on the whole raiden seems to be pretty descent quality wise.
EDIT: the raidens dont have heel ramps, only toe ramps. dont know if youd need them my heel just hangs off a little

Good to hear the positive reviews. I ended up just ordering a pair of used phantoms, so once I get on em' I'll post my thoughts. Keep the opinions coming though, it's good to see what people have to say.
