I'd like to thank all the commentators on the question I asked and I think the outcomes were pretty clear, which I've trapped here. It looks like the end maybe nigh for the fling (see below):
1. Too Expensive (or not enough value)
2. Too many alternative races and places to ride
3. Not enough promotion particularly to younger age groups
4. Not family orientated enough
5. Making a state based series might get some interest back.

So the primary suggestions to the rider are:
1. Dont sweat and go to club races
2. Plan to ride away with friends
