In reply to The Pylon King: There might be harder ones but
Sport
Bristol's Got talent 8c
Trad
Heaven Sent Direct E7
Spiritualise E7
Bouldering
Tombstone f7c
Some of your new ones might be in the HXS bracket though!
This is missing a hold and hasn't been climbed since '02 - would probably be E7 7a now? http://www.ukclimbing.com/logbook/c.php?i=32141 (For would be suitors - the first peg only goes in 3/4"!!)
Only E7 but as far as I know Level Headed still has n't had a clean 2nd ascent. I guess it's probably one of the harder multi-pitch climbs in the area.
