In reply to Chris Craggs:
Wow, this is actually turning into quite an interesting thread.
So the debate seems to be, mixed rock climbing and aid leads to more interesting climbing, but potentially wrecks routes. Whereas a fully stempled route is essentially a ladder and does not provide the same type of enjoyment as moving over rock, but is less likely to wreck a possible future line.
I did my VF in the dollies and really enjoyed it. It's mostly actual rock climbing with the occaisional bit of assisstance. Also, the sense of history there really adds something too.
I have to say, I've never done it, but climbing up a series of stemples looks a bit dull. Still, I suppose all that exposure adds something to the experience.
