Pretty much all of those routes named at the start of this thread are mine. We bolted the routes very incompetently with a hand drill. Taking about an hour or more per bolt. Placing the bolts was such hard work we placed the absolute minimum we thought we would need to get up the routes. Due to some strange outmoded attitudes we had at the time we didn’t top rope the routes before leading them but sort of guessed where we thought the hard bits would be and placed the bolts there before leading the first ascents ‘on sight’. The Youies was such a back water in those days that we never really expected that anybody would repeat these routes. I would be happy to see another bolt added to Tewkesbury. I originally graded it 17 to take into account the trying nature of the lead but guidebook writers decided otherwise at some time [despite there being many much easier routes graded 17 in the Youies]. These days I have a power drill, top rope before bolting to work out the hard bits and place more and better bolts.
