i've seen SP 4 times, and it's gotten progressively less and less interesting for me.  they're very efficient at doing what they do but they don't change it up much - if you've seen one SP show, you've seen them all.  i'm not a big fan of the new album so between that and the fact that i've got my fill of their live show, i'm skipping this tour.  
but if you're a fan and you've never seen them, by all means check out the show.  they always sound great and gary's between-song banter is hilarious, more often than not.
