what works for one may not work for the other.

Personally I have most success over the spring and autumn carnivals. Mainly because horses are aimed at a particular race and I find it easier to work out whether they've had the right prep and form to win. I've had good results metro midweek, but not prov unless it is basically a metro meeting.

I have a bit of a theory midweek. Sometimes many punters leave them alone so that if a big betting stable has a crack at one and you like the other you can get massive divis.
