Honestly I used to pretty much do this. The bookies have caught wise to my game to some extent by winding in a lot of the fringe runners from 30-35:1 down to 17-25:1, so they're not the value they once were. But Siro at 34:1 was always a good shout.
I'm going to have about 18hrs max before the Titans play. So i'm puffing my chest out that entire time
