If you are not aware of it, the Woodbine web site has a daily feature called "Jim Bannon Journals". Bannon is a public handicapper and I have no idea if his picks are any better or worse than any other public handicapper.
But his daily journal also includes a short write up on each horse running that day. This will often provide more detail about the horse and its connections than can be found in the PPs, or point out details that may not jump out from the PPs.
