In reply to Enty: I don't think that's correct Enty. Don't forget, there are routes other than on the slate in N. Wales! There are routes, on the slate particularly, which are designer climbs - minimally bolted. Argue the toss between yourselves over whether this was done in a grand spirit of adventure or if it was a case of grade chasing by the first ascentionists. Either way the end result is a series of classic routes in a fairly unique style. As the guidelines make clear, there is no intention to alter the character of these cherished routes.
There are also some other routes, which were poorly bolted on conception due to lack of funds etc. In many cases the first ascentionists are in fact the people involved with the rebolting, and they are now hoping to equip these routes as they originally intended.
Thats my understanding of it anyway. Personally I think climbing in Wales is in good hands.
