I'll try and find your last thread on this, asked you about this in it, but think it died. But ultimately I am doing something similar this year as well. I have found that this works best in more public games, but I still try and play all sides and totals I can. I am pretty busy this year, so only getting 20 plays a week, including the weekend. And am not even looking at anything but game lines. I think looking at the so-called smart money is good.
But, that can get a little hazy. However, I do lay off favs who I feel are big public favs yet the line gets worse for the dog, thus giving the fav value. I dont know if this matters or not at all, but it makes me feel more confident in the plays. However if a line moves enough I will still take the best line all day every time, I use 2 point move is enough to justify playing what I deem a smart move. I think there is only a small spread where my bet will lose in the long run, thus even this sharp money is not sharp if it is being bet into a bad line.
The other thing I like to see is pin shading juice on the side you want at about that half hour mark. The reason why I like this is because we pretty much literally see that we are catching a peak. and in fact I only am betting the games where pin shades the side I want to bet. This almost guarantees I will beat their line ever time to with at least a low vig out. I dont have any numbers to back up why I do that, but it makes me feel more confident.
I am trying it out and comparing it to just beating the move, just by using a contest with stale lines as beating the closing lines. I don't have the time to actually watch and predict line movement all day. Thus far, they are both up a couple units over about only 50 plays, which is nothing. I expect them both to be up at the end of the year because I am only taking extreme numbers on both sides of what I consider a "true" number. Beating the steam seems to be doing a little better then fading the steam, but imo it is more work if I were to actually try and bet those plays.
