Ricardo48,

boxing six selections in a field of 8 seems somewhat expensive for relatively small returns even though most trifectas will be struck.

Have you got records per field size? And also for quinellas because the TAB take-out is less than the other types of exotic betting?

And also have you got records to see how Zipform's top raters fared because if they have an unsatisfactory Win record maybe standout trifectas as Pauls123 suggests might prove worthwhile.
