In reply to Sl@te Head: As for eventually doing without pegs and using only nuts and cams,sometimes this is worthy of respect.Consulting the creator of the climb would be good manners.
Some routes that have been aid climbed have been free soloed.London Wall being a spectacular example.
If it is better style to do routes without pegs,or less pegs,then presumably it is better style to cut down bolt numbers on bolted routes where there is a bolt every 1.5 or 2.5 metres.Better to space them at 4 or 5 metres;unlikely I know.
There's a reason I didn't put up any routes at Horseshoe Quarry;it's shite.I went there once with a friend who led an E2 on bolts.I asked if it was loose.He said there was one loosish hold.I then sight soloed the route,crux at about 9 metres. If people solo bolt routes or do them on trad gear only,does that entitle them to take out the bolts?
On crap routes,there is hardly any point;just leave it as a clip up.But on a good line there is some justification for tradding it,after it has been bolted,and stripping the bolts.
Placing bolts on poor lines next to necky trad routes is pretty insulting to the first ascensionists and repeat ascenders of those climbs.
There are always going to be plenty of short- neck sport climbers justifying bolts next to classic neck routes.There are enough sport climbs available.Leave the trad classics alone.
Retrobolters seem to think they are doing a service by bolting up ''unpopular'' routes ,or placing bolts within reach.IF A ROUTE HASN'T BEEN REPEATED,THAT MEANS POTENTIAL REPEATERS DON'T HAVE WHAT IT TAKES,SO LEAVE THE ROUTE AS IT IS.THE ROUTE CAN WAIT ANOTHER 20 YEARS FOR SOMEONE WITH THE BALLS. AS BULLOCK SAYS,THERE IS NO NEED WHATSOEVER TO CLIMB EVERY SQUARE FOOT OF ROCK.
