It would be interesting though if there was a proper competition to determine the worlds fastest guitarist by number of notes picked over a number of different techniques (alt picking, sweeps, legatto, tapping etc)....

The fastest guitarist at any givin time would more than likely be some 30 year old guy with no friends who is still living with his mother, hiding out in a bedroom with no windows, books or anything but a guitar to talk to... scary thought!

Seriously though, I reckon real pros wouldnt have enough time for the ammount of practice it would take to become the fastest. But anyway...
