Darkydog,

The problem with putting up systems is that people usually bag whoever puts them up. Also when you find a profitable system most people don't want to share it. I want to make money from it first.

Its not hard to come up with some systems. Making profitable ones is hard.
I'll give this one away which is one I have always liked :

1. Field size at least 8 horses
2. Each Horse has to have raced at least 4 times
3. Horse must be above 55% placings
4. If more than 3 selections do not bet the race.
5. If 2 or 3 selections only bet the highest 2 % place getters.

I use a variation to the above system. It is profitable.

Good Luck.
