Running Crack into Marmalade (shady grade 12 to 11)
Denethor-Ivory Coast (sunny)
Possum (starts shady will get sunny)
Little Hermes linked into Liz after the big ledge (shady)
Vent Crack into Denethor into After the Reiving (I almost died of dehydration on this one in the middle of summer, stupid - sunny)
Hermes is fantastic but isn't 15 (along with quite a few other suggestions by people) and if you aren't confident and/or have biggish gear the P2 layback will "excite" you.
