I actually use a Selle San Marco Regal Ti on my Gary Fisher Rig. Typically this saddle is run as a road/cyclocross saddle but it seems to work just fine for my MTB. I like the way the WTB's look but have never tried one. I usually take around a 145-150 wide saddle. I love Brooks but they are heavy and I wouldn't want to get mine all full of mud all the time and have to get it wet and all that crap. Brooks should stay beautiful by staying on the road IMO.
