well, it has a dw_link on it. go to mtbr and the iron horse forum there for reviews on the suspension design. i have never sat on a dw bike, nor a bmc, but i have heard good things about them both (for whatever that is worth). a guy on mtbr got himself a superstroke to review, but the review is still pending, so..
there is not much available feedback on bmc mountain bikes on the forums i dont think, but as far as their reputation goes, the build quality should be good. and as far as the suspension design goes, well go see the iron horse forum.
here is a link to the pending superstroke review, if you scroll down (after taking enough time to drool over those pics

) you will see this guy who is pretty psyched about the bike and is thinking on buying the fourstroke trail, which is the same frame as the fourstroke 3, just adjusted with a little more travel.

i hope you are going to be able to sit on the bike before you buy it? if you are, be sure to get your butt back here and give us some feedback! best of luck man, as far as hearsay is worth the bike should be good.
