In reply to stp:
Try this circuit at Burbage North:
1. Everything on 20ft walls. Starts at Vdiff, ends at Lost In France (6a), with The Chant (brilliant HVS), The Curse and others along the way. A superb warm-up, 10mins once you've got'em wired.
2. Banana Finger. Classic 6a. Then do the Direct and variations if you can.
3. All Quiet. Superb highball 6a. The other 5a problems next to it are OK too.
4. Hanging Rib and Remergence. OK, we're at full-on UK 6b territory here, but once you know'em they're OK. Solo Mutiny while you're there.
5. Cleo's Edge (great 5+), Roof Goof and Safe Bet.
6. Nicotine Stain, Right Fin and Approach (hard! but apparently HVS...). Finish on the lovely Irrepressible Urge, and go home.
How anyone could ask for a better bouldering/highballing/soloing circuit at around Font 6a/HVS/E1 is beyond me. On a cool spring evening or autumn afternoon it's unbeatable.
