In reply to Rog Wilko:
That's a bit necky for a first VS. Unless you wimp out round the arete onto the easy slab, that is. Also not all that great compared to the other suggestions.
Going back to White Ghyll - that would be where I did some of my first lakes VS's. We rocked up and someone was on Slipknot, so we did Haste Not. And I still rate it as the best VS in the lakes - so I must've enjoyed it.
So I can't really see any major issues with that, Slipknot, WGW, or Gordian Not (the most go-ey of the lot as far as I remember).
As long as this guy's done his time - and he said he's been leading a while, he'll be able to cope with whatever these routes throw at him. They're not walkovers, but do-able, challenging, memorable, and quality rock climbs.
Get on it!
