I always say I don't care for ToT, then almost always like it more than I thought when I listen to it. But off memory, I'm going with Endless Sacrifice as well.
I'm also not as sour as some about the 12 Step Suite; I think it's good, and I like the concept (both in terms of the songs and the format in which they are presented). I would have loved to have heard DT the band tackle the whole thing (and still hold out slim hopes of seeing it in the future).
