Rainlover,

The TAB take is not quite as high as you think. I only have figures for Supertab but I am pretty sure NSW/Qld are almost the same on the main pools (these figures are from last year but I don't think they have been changed since then):

Win & Place: 14.25%
Quinella: 15%
Exacta: 16.5%
Trifecta: 20%
Next Double: 15%
Daily Double: 17%

So Quinella is only marginally worse than Win/Place but I would stay away from Trifecta's - that extra 5% is an extra disadvantage on top of the fact that you can't get approximates from the TAB.

Sorry don't have the figures for First4/Superfecta on NSW but I am guessing they are at least 20%.
