In reply to kipper12: If you visit www.markreevesclimbing.com and click on the Safe Slate link at the top of the page you will get a list of all the rotues that have been re-bolted, along with some info on which are more sports climbs and which are like bolted trad.
My personal recommendations are for sport.
The deceptive Dyke - Looning the Tube area - F5
Peter Pan - Serengeti - F6a(+?)
Drowning Man - Cig-Arete Level - F6b
Bolted Trad
Loads around looning the tube
Launching Pad, Tower of Laughter - Dalis Hole both - E1 (two bolts to top)
Mentil Lentils - Vivian Quarry - HVS Bolts and wires
Psychotherapy - Vivian Quarry - E2 bolts and wires (it is a one move wonder right by bolt)
