I ride a Marin Wolf Ridge, which at 140mm suspension does not fall into your criteria, but as an AM bike I find it brilliant, it more than does me DH - I ride the FOD, Aston Hill and other places on it, mates who ride major DH bikes have been pretty impressed with it. I run coil Pikes rather than the OE air, but have lightened it with a custom spec (bought the frame, then built it up) - weighs in at 32lbs.
The OH rides a Santa Cruz VP free, his is setup for DH running Boxxers, but it could quite easily be a AM/Freeride bike with single crowns. Nice and strong with 150mm rear too, but with the Boxxers it's over 40lbs.
Would recommend either!
