Nope. Just need an acro series with a min. of 2 flight, so like BHS-BHS series would work for a minimum. Also need 1 leap/jump requiring 180 degrees & min of full turn. Lastly, just need a min of B dismount. Really don't have to have a BT or aerial, but would probably be a good idea if you did have it. I would think if all you did was the absolute minimum for a 9 routine, you'd get hit with a composition deduction.
