I think the trainer angle is good (Hough and Jerkens ),however the thing I really like is if a horse is working over a track that is really slow and showing seemingly slow works ie .the training track @ Saratoga .If I'm not mistaken Jim Bond has 'The Spa' as his home base and he usually sends horses to the track ready to run .I think horses tend to get some real bottom from these types of tracks ,and I have made a few good scores with this angle through the years .
