In reply to The Ivanator:
You called
Wyndcliff Quarry is a top convenience crag, ideal if you don't have long, or you're chancing it in unsettled weather. Or spend the whole day there and tick millions of routes! If the clouds open you can be off the rock and back in the car in a few minutes.
It's probably wise not to have overly rigid expectations regarding grades - some of the starts are thin and bouldery, and may feel disproportionally hard. A clipstick is useful, as some of the first bolts are quite high.
Upper Lift:
Not the Arete 6a, THE END 6a+ and Sometimes I Won't Thrill You 6a+ are worthwhile, as is the newer route Chepstow Killer Appliances 6a+ (see 2012 supplement for this). Better In than Out 6b+ would be a good little redpoint project, as would the retrobolted Shin Gi Tai Direct 6c+ (see supplement) - it's soft touch, probably only 6b+, so get in there quick while the grade still stands!
Lower Lift:
One Tooth Short of a Smile 6a+ (max 6a if you use the bigger holds just right, prob 6b if you don't) and Still Stuck on You HVS 5a (like a 5+ sport route with the first bolt missing - need a couple of wires) are both quite good. Finishing Touch 6b is good but has a very technical start: hard to onsight.
