Anyone is who been using the sheets(TG or Rags) for the last 15 years or more has to admit that winning using the sheets alone is much, much more difficult now than previously. Gone are the days when a "sheet" horse would lay over the field and pay $15. Pattern plays may still work but you have to have plenty of money (buying sheets daily) and plenty of time (pouring over the sheets several hours a day)to pick out selective plays and stay ahead moneywise. In the old days, us weekend warriors used to be able to buy a couple of tracks worth of sheets and hold our own.....sometime even winning a few weekends in a row. Now, with the more popular sheets, the Beyer #'s, and other tout services using sheet methology all driving down the prices.... forget about it!
I still use the sheets because they are the best handicapping tool currently available but I am desparately trying to find something to augment(pace, class, readiness???) my sheet fig projections so that I can have some fun winning again on my biweekly forays to the track.
