Ridden it and only a few spots concerned me. Granted we didn't run the chicane, we did the bowl turn that day. Main thing besides safety I heard from a friend who used to be a CR back when the place opened was that it was too hard to ride that track and try and turn your head around as a CR and direct traffic, etc... Then of course the safety doesn't help.
Though I think some people are somewhat fooling themselves by thinking main is a whole lot safer. Shenandoah at least is pretty slow. Main there's a lot of walls that are way too close considering the speeds you can run. Thankfully the air fence limits the risk some but turns 3, 4, 6, 8, 9, and 10 are all on my list of wish the walls were further away. Will I stop riding there? nope. Does it make me think twice running with a group who doesn't use air fence vs one that does.
