As I enjoy riding singletrack, with rocks, roots, small drops, stream crossings and I also enjoy riding pavement, I'd be missing front susp. when off-road, or the efficiency of a road bike on pavement. Guess if I HAD to settle, maybe a hybrid with front susp (would probably switch out stock fork for a better quality one) and which would accept a larger tire. I started riding off-road on a rigid mtn.bike, but don't care to go that way again. Very glad I don't have to settle for just one type.
