In reply to slab_happy:
I'd say there's some classic eastern grit HVS'S
Goliath's Groove
Great North Road
Peapod
Valkyrie Pinnacle
Right Unconquerable
And of those, GG is possibly the easiest (or tied with Valkyrie). They can all be safely protected, and are all pretty hard work.
They're all pretty much a "step up" from any VS you'll find, so I couldn't give you any routes below the grade to say "do this and you'll be ready".
I personally only onsighted one off the list, but I did hit them all fairly early on. Maybe if you want to be sure of a clean ascent, save it till you're steady at HVS?
But if I really was pushed to suggest some classic hard eastern grit routes for VS I'd list:
Excalibre at Lawrencefield
The File at Higgar
Fern Crack and Count's Crack at Plantation
Agony Crack and Step Ladder Crack at Popular
The Mall at Millstone
But you'd probably be better prepared climbing slightly less classic HVS'S that are hard but safe...
Divine Providence (or whatever that slanting crack in Black Hawk area's called) and Rugosity Crack at Popular
Any of the HVS's at Millstone
Terazza Crack and Surgeons Saunter at High Neb
But in all honesty, none of them are reeally like GG. I slipped off back and footing the start of GG on my onside attempt, but cruised the upper half, I've since gone back and jammed it cleanly, but that first "dogged" ascent is the one I cherish more.
Good luck!
