I've never used the roving banker trifecta,,just to costly....

What works for me Crash is of course the banker trifecta,,but have a level stake..
say 150 ... in a race with 12 staters..
banker tri costs 110
so with the other 40 i'll have my banker with say my next 2 raters..
this 20x for 40...
depending on the banker selection..if you've selected a good price winner as your banker then you might go even wider ,,say 3 or even 4 selections for 2nd and 3rd....

you could even just go 1/2 for the banker field tri which would only cost you 55 (for 12 runners)and have a level stake of 100 .

when theres a large field then Stix is right..Nswtab is great for this as you can just take a percentage...i also like the Nswtab as they always underestimate our Qld horses down there...(starcraft started at 50.s ,, i/2 that on unitab) Dont tell clang and a few others were the same....

Interesting if you looked back on even just this thread and see how you'd have done ....,,,especially if you've rated the winning races 1,2,3 ..
