I'll second this. If it's true exposure while rigging traverses that you're after, then anchors 6-10 on the CNCC topo for Main Shaft will take some beating. You don't even need to wait for drought conditions because you can stop a few metres down, turn around and then derig for double the fun!If exposure was what people were after, and lucky enough for prolonged dry weather, then GG main shaft would surely give some exposure? (Not had chance to do that one myself)
