I thought I would chime in here. I don't do very well in IMAC and sure not in 3D, but I have help put on a couple of IMAC contest.
I assumed (you know what that means) that freestyle was different than 3D. Freestyle was doing IMAC maneuvers flowing with music with maybe some 3D mixed in.

Pure 3D was like XFC with music with bunches of high alpha.
