No - the best thing for GA is to speak with a single voice. Dividing us up into small interest groups means that we can be picked off and ignored by the authorities.
I know some of 'top-end' GA who have already had to fit Mode S don't have a lot of sympathy with low-enders 'barging around the sky invisibly. But surely we all need to take the view that all new regulations have to be reviewed properly and none should be imposed at disproportional cost.
As mentioned earlier, the £1500+ or £5000+ for Mode S has to give the owner something back worth that sort of spend - and it doesn't for microlighters, glider pilots or PFA pilots.
