I kind of suspect so, because TobyMac (whose music I absolutely cannot stand) owns the label so they're probably kind of obligated to tour with him sometimes.
Yeah, I think that's fine. Relient K does that winter tour with him a bunch, so its probably not a huge deal to do from time to time. Consistantly, though, the tours they get on are either very small or outside of their rock sound.
I think this tour with Relient K will be great for them. I saw them with Rk a few years back.
