i have a dhx and it feels great in the small bumps, you just have to back off the pro pedal. the nice thing about the dhx for a DH bike is that if you race, you can adjust it better than a roco for the course. if it is fast with a few big drops, crank up the pro pedal and the bottom out adjustment. if it is super technical, back off the pro pedal. the air valve basically adds to whatever you set the pro pedal and bottom out at. basically, it's a three stem system, the pro pedal in the beginning of the stroke, bottom out at the end, and the boost valve connects the two. the roco has no platform, so if technical stuff with nothing that really requires you to hammer on the pedals is what you ride, then the roco might be your best choice. i havn't heard that the roco is too stiff for big hits at all, i have heard that it is just overall plush and smooth. and yes, the roco will be a little better for the small bumps, but the dhx can be as good if dialed in correctly. both are great shocks, just for different types of terrain really.
