Might as well grab some more info off you guys while I can...Is it worthwhile betting on races for 2 year olds, fields of 7 or less and the cup meetings at non metro courses?

Choosing winners/ placegetters in races where there are large fields (esp 2 yr olds) seem like a lottery to me...Having no 3rd place dividend might cut down your opportunity for a place bet (have been caught out so many times before that I decided to keep to betting on 8 or more) and I have found some value bets in the non metro courses' cup days...

Or does it depend on just whether you criteria produces standout (potential) winners...thank you...
Cheers...
