I've never seen Schenker and I'm curious to. When he's on, I keep hearing about how he's one of the greatest of all time. When he's off, it's the stuff of legend, a trainwreck for the ages that has to be witnessed to be believed. I've never read or heard of a lukewarm "meh" reaction to his shows, only one extreme or the other. I feel like it'd be worth checking out in either case.
Also I really liked that Slavior album from 07.
