My disco was always my daily driver. Did some of those trails with OME lift and 235s, but if you keep on that setup, you will break axles, drive shafts, differential, easily bends track rods, drag link, trailing arms. Never did Rubicon. Most of the time after '05 I was wheeling alone or with other vehicle that were not Rovers, so I used notably more care. Always easier with a team of experienced rover people.
So then went ARB, GBR Axles/shafts, 4.11. Complete RTE and Rockware setup with 255s (not quite 35). I think in was 4-5" lift. It was far superior on any trail and was still decent on highway. Never trailored. Never saw another disco do significantly better with retained springs, as an example. Winch time reduced a lot, part lift/tires, part lockers. Nothing looked too out of place on that truck. Wheels still within the body. But some on 35s and 37s could definitely handle trails better, a few drove them to the trail and daily, but not many.
I bet holy cross would be much more difficult now. Haven't seen It for 8 yrs, but few colorado trails have not increased in difficulty. Holy cross has likely been significantly chewed up and eroded. But, only a guess.
