Dick,
Since the powers that be have largely removed your "incredibly unsafe" E airspace, especially non-radar, the majority of 30 and under turborprops are no longer threatened by VFR off-freq higher flyers.
The main threat to my safety is you and your low level bugsmasher mates swanning around making broadcasts with their ears closed in MBZs. I have personally been concerned for the safety of me and my pax on three occasions in the last 18 months because of the stupid statement you had inserted in AIP "Direct Pilot to Pilot dialogue should be avoided where possible".
The only protection we have against these types is TCAS, and they don't have to have a transponder. YOU mandate transponders for the aircraft that will kill us, and we'll push for TCAS in the 30 seaters.
