Well Michael, I think if you just stick to what you got so far, you couldn't go wrong.

My BiL just rang, out of the selections today, two early races paid off already and he is quitting for the day.
Good one at Moe race 2 Cheilani at $5.5 Supertab and a place somewhere else, I'm not betting today, so I'm sure where.

Good luck

Ps, keep looking but, I'm always looking for new angles myself!
