Here's a video of Lawson Rollins' Persian Night that I came across the other day. As you're watching this video - yes, he's a classical player - watch the kind of moves he does. You'll find shredding in here that would make Steve Vai or Yngwie Malmsteen grin in approval.
Watch how he uses his index and middle fingers for those amazing runs. Also notice his fingernails... a lot of players serious about using their fingers like cutting their nails in that long pointed fashion, while others use the fleshy part of their fingers instead.
If you can, try and take a single lick that he played and see if you can do it... even if it is only at a glacial speed!
Oh, and checkout those insane arpeggios around 2:30!
