How about shifting this discussion away from miles per hour and onto another aspect of what makes a guitarist good - choice of notes, which is irrespective of speed.

I'd like to ask you. What guitar solo do you like best from the point of view of musical taste?

Here's some of my favourites, some well known some less so:

David Gilmour, Wish You Were Here, Money, Another Brick in the Wall

Robben Ford, Don't Let Me Be Misunderstood

Corrado Rustici, Sens Una Donna (Paul Young and Zuchero)

This is just for starters, to get the discussion going. Oh and have you noticed? There's no metal here.......
