> We will be cleaning Acheron as soon as possible
I did Acheron yesterday. Thankfully I seconded the 'scrambling' start, which incidentally we both thought is quite horrific, even in its current, partially cleaned state. Can I suggest you take a pragmatic approach to cleaning it, basically by not bothering, as the first slab overlap can instead be easily reached by climbing the first few metres of Doom. IMHO, the scrambling start adds nothing to the route itself, other than the highly questionable virtue of an independent start.
Elsewhere on the climb the vegetation doesn't detract at all from the climbing and I agree that more footfall will improve things greatly. However, if you were inclined to do some work higher up, then there's the not so small matter of a jammed wire on the crux chimney pitch. It's a DMM offset which looks as if its been there for a year or so, as the wire is very rusty but not as yet rusted away. It's jammed in quite a crucial bomber placement, part way up the initial back and foot section. With no alternative placement to be had, can I suggest that as part of the eventual clean up effort that someone considers abbing down - or be lowered down - with a hammer and chisel to remove it? It could be done by a suitably equipped second whilst climbing the route, but would be far easier done on abseil. The nut's very well jammed in, (perhaps after holding a fall?) and will need some force to remove it. You'll appreciate that once the wire itself rusts away, the placement will no longer be useable and it'll make the crux significantly less protectable. Just a suggestion - as I fully realise it'll be no small matter to do this.
Good effort on the clean up plan btw. As someone who first climbed on Cywarch in the very early '80s, when it wasn't unusual to see half a dozen teams on Craig Llywelyn and queues on Doom, it's actually quite unbelievable to note the difference that a lack of visits have made since then. There used to be a very well worn climbers path beneath Craig Llywelyn, but there's no sign of it now as it's been totally grassed over and what used to be a well-worn zig-zag trench of a descent path (Llwybr Llywelyn) has also long been reclaimed by the vegetation.
