If you're not a regular user of Formulator, the Keeneland meet is a good time to purchase monthly/10 card package (use public handicapper discount unless Steve has one to offer).
To your point, this meet has some unique trainer angles so filter for KEE specific stats.
I'm a believer in horse for course angles at KEE - especially on the turf. When looking at dirt races and trainer angles remember that KEE was poly until the Fall 2014 meet.
I read Jeremy Plonk's daily analysis. Not for picks but some historical context and emerging trends on how runners from various circuits are performing at the current meet.

Pay attention to first crop sires - A win at KEE goes a long way in building steam for young stallions.
