Actually i think a norwegian guy with the name Paus (not Ole) got the world record.. but his music sux..
I would say Jason Becker, Shawn Lane, Petrucci, Gilbert, Romeo, Tony MacAlpine, Greg Howe, Vinnie Moore.. etc.. u really can't say who is fastest of thoose guys..
btw.. Holdsworth is good.. really good..
Malmsteen ain't that fast.. but personally i like his playingstyle.. he was the first.. and will allways have a place in my heart.. Still, guys like Romeo plays very similar, and faster.. (I'm not going to say who is best, cause i can't really say decide, Best ain't the same as Fastest, still i like SyX more than RF..)
