I usualy start with 2 string sweeps(economy picking) al la Rising Force solo, than three, a little bit on four, and than finish off with 5 and 6. Usualy when I´m ready with four str. I go back to 3 str. sweeps and the difrence is huge compared to first rime. Than at the end I finish the session by playn´ some harder sweeps, mostly combined with slides. Pretty much Jason Becker over those.
