I must check out that legato guy, and I know that there´s lot of cool stuff you can do with legato because I listen a lot on Satriani and he uses it frequently and he is good. I think that Dimebag Darell is another magnificent legato user. But they are really diffucult because of all those finger streches. But my main influences comes from Petrucci, Gilbert and Malmsteen and they don´t use it so much. Mostly they let the pick do the bussiness.
