I agree with all that w934 so I won't quote you.

The place prices on odds-on [or close to it] is an area that a bit of dosh can be made, but for the effort involved ....forget it. I'm happy in the $3 to $7 SP win area [mostly]. I will take long-odds if I spot something I think has a good chance who has odds way over what I think they should be. In the end it's all about percentages and trying to get better odds than the house for most of our winners.
