Fish: It seems the best way to get a workable middle going is to bet as early as possible, and of course be correct. I haven't hit a middle yet, but getting chances.
Seattle has moved nicely, but Dallas starting to slip a few cents on me. I just opened at CRIS to get early lines, but hate paying full juice. I like to bet at Pinny to start a middle, then wherever I can take back.
I don't usually bet equal amounts. I usually bet 2 units on early pick, then 1 or 3 units on other side, I still have half-time to fine tune it. If I get stuck with a line that goes against, I just keep it, and maybe adjust at half-time.
I get more money out there, but risk isn't so high, and I get shot at middle ( hopefully).
