In every interview I've seen, he seems like a nice chap. That being said, and of course this is all speculative, is I think SW should just concentrate fully on PT. PT is his strength. And he's just a part of the band, a big part yes, but Barbieri is masterful at what he does. Harrison is one of the best drummers in all of music, and Edwin is a superb bass player. Take anyone of those cats out and it wouldn't be the same. I've heard Insurgentes and Schoolyard Ghosts both good albums. But, as with FOABP, both of those albums started out strong(first 3-5 songs) and the remaining songs tailed off and didn't hold my attention as well. I just believe at this point in his career, he needs to put his efforts completely into PT. And in the future he will develop into a premier solo artist. I don't care about all his perceived pretentions or attitude. Just create and record good music. I think PT has slipped a bit since DeadWing.
