key race angles

[amazingD]

What would anyone suggest to look for in the quick sheets concerning the key race angles. Does anyone find that they are more effective if the horse finishes in the top half of the field. Just want to use them as a factor in improving my spot plays. Thanks All

I think the horses runing 2, 3 , or 4 in maiden races would be bets....stakes races mean little I think too because most of those are horses that win alot.
