I also find it odd that they weren't charted in "HTML Rulez D00d" when the same authoring company charted double kicks in "Collapsing".
That's really odd, cause I felt there was a part of Collapsing, pretty early on iirc, that was pretty crazy foot-wise. Like, they could have removed 2-3 pedals and no one would have cared. Never ever would have guessed it was the same group. Probably different people.
