That doesn't sound difficult to tab, it's just difficult at times to actually hear what Jeff is doing with the leads. I don't know if it's my headphones or whatever but it seems like the lead is a tiny bit too quiet and I can't always make it out.
I was also listening to Jato Unit and thinking my song for the Forum Album is very similar to this stuff. It starts off with a theme, and then goes into a fast melody with a 3rd harmony, then goes into a guitar solo, then more harmonized melodies, then another solo, then a variation on one of the earlier melodies and more solos etc, while the whole time, the rhythm guitars are just playing chords with no riffs at all. At first I thought it was quite boring to have it that way, but if it's good enough for Jeff Loomis, then...
