Just as a banker ...roving costs more
about 3 times as much....
easy to work out the cost
No of picks
x No of picks for 2nd -1
x No of picks for 3rd -2

Mr ponsford Tri cost me $36 for a 1/2
if i roved it would of cost $108 for 1/2 so you really are hoping for a couple of roughies to fill the places.

Te Stamen tri costs twice as much because it was a large field.

I've been doing this alot lately ..theres nothing worse than being super confident on a horse to win and missing out on the tri because some donkey has jagged a place.
