@Capt Ron and I were noobs last year and ran Hell's Revenge and Flat Iron. Hell's really didn't pose too much risk to body damage. We did take a couple of bypasses in spots and stayed out of the escalator and had crazy fun. Big tip- listen to the guys that have been there. Wade and Mark plus others have good experience on what the right line is. There is more than one line and what works for one may not work for another. I figured that out when I went wheels up on Flat Iron. Mark reset me and sent me on a line I didn't see anybody take up to that point and I walked right up it. Again, listen to those guys, they won't send you into harms way.
Flat iron had different challenges over Hell's. More ledges down and up vs the sheer climbs on hells. Ron and I took a couple of the bypasses to avoid harms way. I was feeling more confident and took on the hard climb up the dome that I went wheels up on but with the right line it went right up. I did break a front axle shaft a little later and had to bail out with some help on another ledge climb. Red was with us on Flat iron and with little to no lift on his CUCV and 33's went further than we did without any issue. That proved to alot of us how well they can do relatively stock.
The traction is nutty out there. It's so good it takes a little to adjust too. I'll say it one more time, listen to who's spotting you. They will put you on the right line to succeed. I say that not knowing your experience wheeling. I've got a ton of time wheeling in Colorado in the mountains with loose rocks and nowhere near the traction Moab provides. I didn't try to overthink it or not believe the spotters or think I knew more than they did. Moab is like nowhere else, those that have been there understand it and will share with those that are new.
Best of all is wheeling with a bunch of likeminded folks with very diverse trucks from mild to wild. Some of the most fun I've had wheeling ever.
