In reply to this question, yes I will also definetely look at the tipster tips.
When I choose a lay bet, I first look at the dogs with the lowest points. Looking at the image below this would be Trap 1, Trap 3, Trap 4.
Another criteria is that I do not lay dogs with more than 15 points.
Make sure that your selected lay bet is not picked by any tipster to finish in the first three places.
So this leaves us with Trap 1 and Trap 3 as our selected lay bets.
I now choose to lay dogs between the odds of 2.0 and 12.0 it was different before, but this is what works best for me.
If you are using BetBotPro (BBP) make sure your settings only allow you to place 1 bet per race. (example below)
