All through Bodog's racebook B. If the results keep up for awhile though, I'll move some $ into either BetCris or Nine.com, as I noticed that they offer rebates for horse wagers.
I'm pretty pleased with the results, and with a little cushion and some records on the cappers, would like to hit some multi-plays.
Here's what I'm working with:

At the 1st one, I basically have just been looking for horses that show top3 finishes over the last 3 races and don't have huge gaps or really short turnarounds since their last race. Also prefer "closers" or "wire to wire" to "early speed" or "runs evenly."
The people on the 2nd one generally offer decent summary analysis.

Anyone please feel free to add any resources you dig up -
