ubetido,

Don't fall into the trap of needing action... make the best bets possible and only part with your money when your confident in your selection.

Its better to have a stricter criteria in most cases rather than have more action.

Something to note from research is that horses actually perform closer to expected on slow/heavy then they do on dead ground.

If I was you I would also rule out dead tracks. I believe track bias is more prevalent and can be a major issue with dead tracks.
