"Some will undoubtedly disagree with this, but perhaps inside the MATZ might actually be a less congested place for AEF aeros, rather than in a choke point in Class G airspace."
Minimum height for aerobatics (for AEF sorties) is 3000' agl - ie the top of the MATZ. You cannot, legally, perform aeros in the MATZ.
