i'm keen , $10 each ?
Tell me if I'm out of line but I was thinking of $30 each?
Using something based on the patented ratsack method, will put forward the suggestion of two tipsters each Saturday, one venue.
Each tipper picks an 'A' selection and a 'B' selection in each leg
We take one ticket with all the A's for $5 : 2x2x2x2 = 16 combos = 31.25%
We take a second ticket with all the A's and B's for $25 : 4x4x4x4 = 256 combos = 9.7%
Even if there are just 3 of us then we go for 3 weeks - which is $10 per week.
Just a suggestion. Open to ideas.

Oh and I vote ratsack as treasurer
