I.M.O 2 tracks that are pretty decent for matching but get lost under the radar a bit:
1) Indiana Downs lets you get some pretty honest reads. It is a fast track speed wise but thats good cause it keeps you and your "Mind's Eye" on picking fast horses without worrying too much about t-t stuff. Early evening start is kinda nice in the warm weather
2) Arlington Park consistently seems to give at least 3-5 races a card that are kinda nice to work and match. The poly doesn't seem to be wild there and fast horses are fast horses. Even the turf seems to kinda give you a fair shake.
