In reply to mrjonathanr:
Hi, yes, for background refer to the summary doc I presented at the Cymru N Wales BMC Area Meeting last month: https://community.thebmc.co.uk/GetFile.ashx?did=3899. There was a full range of views expressed on the topic.
There are plenty of precedents now for replacing old hammered pegs on trad routes in North Wales with drilled/glued runners e.g. Citadel on Main Cliff, Chicama (E9) at Treaddur Bay, Rhoscolyn, Clogwyn yr Adar, Castell Cidwm etc. You may have clipped one or two on Quickstep at Forwyn.
Regarding Tremadog, specific routes mentioned for discussion include Swift Undercut and Llanberries which both rely on old pegs and don't get any traffic now the pegs are knackered, so what to do? Replace with hammered pegs, remove the pegs and re-climb without, or drill and glue a longer-lasting runner that could last 50 years - to be discussed...
