Thanks Sportz,
The best systems are the simplest. I will use it wisely!
Just looking at some simple stats, teams travelling often struggle. Therefore unless a complete mis-match (top vs bottom or team in red hot form) i reckon the home-dog system must be as good as any other. Only exception this weekend were the Steelers who are looking a very good side this year and at the moment are playing like it.

Hi Andrew,
Not too sure about Saints - Giants.
Might have a little dabble on the Giants purely because they are playing at home.
