In reply to Rob Davies:
I really don't mind polish, it's a part of climbing on limestone and it's not going to disappear so I just accept it.
When I first started to climb on limestone after sticking to grit for years I hated it, slipping around on horrible shiny holds, trying to hang onto sharp, crozzly pockets while placing gear that looked like it was either going to slip out or shatter the rock.
But now I really like it. Foot placements can make subtle differences. Do I use the polished foothold, or do I use the unpolished poorer foothold? And if you're not sure how to do a route, you can often tell how the hundreds of ascentionists before you did the move.
Just got to learn to love it!
