I haven't got out there yet to check it out but here's a few suggestions;
10. Broomstick climbs from the ground with 9. Bewitched being the variant heading off left. Also there were 2 bolts without brackets on bewitched - have they been replaced?
15. Warlock - looking at the photo I think the traverse goes lower and more horizontal.
12. Hollow screams V is actually the original, which would make 11. Hollow screams direct.
witch LH variant steps left at roof and finishes as for 14. unnamed. Not a bad variant and should be even better with the new bolt.
14. Unnamed looks very similar to First Touch 21. I was actually there on the day of the first ascent & I think it pretty much followed Unnamed but finished more up the blunt arete left of Witch crack rather than up the centre of the witch left hand variant.
Witch RH variant - two stars?? I seem to recall this climb is easily avoided by reaching far right to the buckets of Wishful thinking. I'm sure the climbing is better if it's climbed direct but it is squeezed in a bit.
