Just to add, there are a number of UK quarries that still have a longstanding trad ethos, e.g. Millstone and lawrencefield in Derbyshire, Cambusbarron in central Scotland. And even some quarries where bolted routes exist have trad routes that the local community would object to being bolted.

This is probably a better answer, even a 60m sport route would require more than the 80m commercially offered if lowering/abbing from the top as standard. I've climbed multipitch sport in 2 pairs of climbers, both with 60m so we could 1-climb longer pitches. 2-make longer abseil's. The 2nd rope can either be towed up, or in the case of Sharma and the like, probably be carried up by a willing cameraman.

Just to add a UK perspective, 'cragging', or single pitch climbing was popular as a sport in the early 1900s in the UK. JW Puttrell climbed extensively on Wharncliffe crags near Sheffield in the UK.

Agree with @requiem a waterproof hardshell will sacrifice breathability that can help keep you dry. The last thing you want is damp underclothes in those temperatures.

I'd go with option 2 if you really want to lower them, makes sense to do it from the top.
