The overhang on Rebuffat route can be climbed free at 5+/6a, too. In some guidebooks the route is rated TD inf. A normal rack with nuts and cams should be enough.
from the routh description i think that your talking about a routh that called in some of the guide books as cosmic spur, i was climbing it this summer and it was very enjoyble, if that's the routh i'll be happy to put in some more info, topo and photoes, so please let me know.
