Considering the fact that 99% of tipsters are diabolically bad at making selections which win in the long run, have any of you considered paying for their information and LAYING their selections on the Exchanges? I do that for handsome profit from the Derek Thompson tipping service!

However, I have also read about the following tipsters who recommend losers to be laid on the exchanges. Have any of you tried them and are they any good?

1. Isiris Losers Line
2. Racing-spread.com

If you have, can you also let me know over how long a period they've been making a profit/loss. I tried the Isiris losers at Aintree - but both came in! They assure me that 90% of their selections, which are favourites or second favourites do not win, but I want to know to what extent that is true.
