In reply to jonny2vests:
As this route free climbs Mescalito and New Dawn, I'd imagine there's a fair bit of tat already insitu. One thing that has struck me having watched Tom Evans's El Cap Report over the last few months, is the amount of fixed stuff on El Cap. Looks like Raven Tor in its aid era. Bit bigger though, obviously, and made of rock.
Another interesting aspect was that I read that in between attempts, aid climbers had managed to break a hold, obviously changing the moves a bit. So what happens if he manages to free the entire route? Aid climbers will still climb Mescalito and New Dawn, and will inevitably change the route from time to time. Have a look at Mark Hudon's trip report on The Shield to see the damage that has been done to that route. Pegged out cracks that started as Rurp cracks, that are << worse than Serenity Crack >>. One wonders if this route may be a temporary affair...?
