This was really difficult for me. I chose Disruptr and Heaven's End, although I also considered Coast and Terminal.

This album is just too damn amazing.

1. Disruptr
2. Heaven's End

for me.
top 3 would be Ki!

I like the first four songs as a unit, but individually I prefer Trainfire.
Although now that Casualties of Cool is out, I prefer CoC > Trainfire, but hey, I ain't complaining.
