Allways ran a rear Freehub and allways will, i love my King to bits and will never go to anything else, from what i've seen of FFW so far it seems like bad idea, my mate runs a Eno on the front with Echo cranks and a Echo bash and what he has been though with it it's a bad idea to go FFW if you want to change, not saying FFW is crap ... it could just be him, becuase he doesn't really have any good luck with bikes . His Eno has had new pawls put in, new service and still yet skips like a bitch ... also the freewheel didn't really fit right, he had to grind down his bash, file down his BB and do a shit load more to make it fit nice, and still it's a very tight sqeeze and his BB is at the longest. Rear freewheel seems good, my mate runs a Eno on a DMR revolver hub and he's not had any problams with it at all, nothing ever comes loose and is allways running spot on. I've heard quite a few bad things about FFW but also i've heard good, personally if i was to run Freewheel i would run it on the rear just to save any hassle. But i don't think i'll ever run a freewheel anyway, i've allways ran a hub and i prefer the feel of a Hub, rear freewheels feel really solid and mega hard and i don't really like that i like a bit of sponge there if you know what i meen, not like a spongy hub or anything but my king just feels softer at the pedals compared to a Eno.
