No comparison, it is nothing but rocks, boulders and ledges of various sizes. Very technical, need right line, you can't be overly aggressive a lot of the time. Very demanding, after 8hrs of wheeling on first day I was bagged and ready for a cold one. A passenger that can spot passenger side for wheel placement and body positioning is invaluable. Cadillac hill was a blast, I actually only puckered up on big sluice, funky drop with off camber and climb (kinda hard to describe) , didn't bother my wife, she was busy spotting passenger side for me LOL. I am home all weekend, drop by if you want and check out the dings and dents on the XJ.
When I get some time this weekend I will put some pics online. Son is gonna edit Gopro for me I will post it online. One of the volunteers had a full frame XJ running coils and 4 Link rear. That beast you are building would be right at home on the Rubicon!
