I'd guess that you will find more big-mountain folks over on biglines.com.
That being said, the Basin has a pretty tight crew who compete, especially in the Colorado Freeride Series over in Snowmass.
I'd also have to give the Taos event (skitaos.org) really high points for organization and vibe. One of the best events around, IMO. The mountain is also a skier's paradise (no snowboarding, gnarly terrain). But if you like the park and pipe, Taos won't have much to offer. Strictly a big-mountain experience.
