From everything I've read (Slash's book, Mags, Interviews, Etc) Izzy is very introverted and doesn't like the "grind" of touring. He likes writing and recording but he doesn't like life on the road. When Gn'R was trying to record the Illusions Albums Izzy went back to Indiana for a while just to get away. He also went back to Indiana when we wanted to get clean. He's just not into it.

I'm with you UKJovi - Let the Deleo bros. deal with Weiland. He's better suited in STP than VR anyway. I feel for Slash though. The guy just can't seem to find a singer who isn't a total head case.
