Hi Stix.
No real system any more for me Stix..i usualy just bank with the field / field.
but it depends on how short my runner is and also if i have other runners..
if i have 3 selections ..its usually a 3/7/7 which costs $90 ect..with that i'd also have my most favoured runner as banker and the other 2 selections 2nd and 3rd for $5..which would cost $10..
I dont have a specific formular with the tris...i have my serious bets already planned so the tris 1st4's and trebles keep my busy during the day..
i always take my ratings...so i'm not just picking anything ..
I have a great record with the tris , trebles and 1st4's....i always hear negative opinions about them ...but i can see no reason for them..
i once was the only unitab punter to jag a 1st4 up in townsville oneday..
also was only 1 of 3 people to jag a tri just recently....i think they're great fun.....u can sometimes have a run of outs but i think i have a lucky habit of jagging nice priced winners which usually means nice priced Trifectas..
Good luck
