<On the weekend at Oran Park he broke 3 spokes. He check the spokes
after every session.
With competition rubber, I wouldn't be using standard wires, the dayton
72 spokes are good wheels and they are obviously not quite good
enough for serious racing.>>

No wire wheel is.  If you want to run wires, with modern tires, buy new ones 
and toss them every couple of years (or longer, depending on what your neck 
is worth to you). They flex and the spokes work harden and crack  where they 
enter the wheel (they take a bend at that point).

<<When you start getting more serious (comp rubber for example), I'd be
putting knock-on alloy wheels on the car.>>

Wrong way to go as well. Some, at least, of the fancy Minilite look-alikes 
are weak and break. A friend managed to walk away from the failure of one of 
those wheels at speed on his E type. Fine for the street, bad for racing. 
Far better to convert to studs and run alloy (aluminum or magnesium) bolt on 
wheels.

I used to run magnesium, before I 'retired' to do only vintage, and went back 
to stock Twincam wheels, which seem to hold up alright. Don't even think 
about stock MGA or TR6 wheels - they are garbage - I've ripped the centres 
right out of both of them. People don't seem to realise what stresses modern 
racing rubber puts on wheels and suspension.
