Both lower Ajax and upper Woodpecker are fine, no risk of body damage on either with reasonable care. The road crosses the trail regularly, so there's ample opportunity to bail if you get uncomfortable.

Funny, if I'm seeing this right, this is one spot we took the 'bypass' on, and the bypass is what we almost flipped on. There's a pretty tight spot coming in to this, which is where I got my quarter panel punished.

Good luck with Upper Ajax. I just ran that yesterday with another group, and it's nasty. A couple of us took some body damage (me included), and every truck was on the verge of rolling. We had to tie straps to the top of the trucks and have several guys pulling to keep the trucks from rolling...
