I reckon we ALL have tried various methods to come up with a winner.
I'm sure if we each post a couple that we've tried- there'd be thousands of selection methods. Here's a couple.

Horse finished "42" or "24" last two starts & has a "C"(for won at course and distance).
Also, the old staple- any horse Race Number, Tab Number & Barrier number all the same.
I even had a guy tell me if a horse had two x's(two spells) in it's formline(last 4 starts) and was between $5 & $9 prepost- GET ON!!
What have you got for us?
