I'd like to see the transition layer raised, to allow easier access to the 10,000 to 14,000 level for VFR also. I would like to see the USA 18,000 feet used, as an altitude and FL, but if that seems too high or gives the FSS more work to do passing area QNH, the NZ (ICAO) 13,000 would be at least better than what we have right now.
