From personal experience this service usually gets off to a wobbly start, but by mid-October it finds its feet and begins to motor.
Unfortunately, this year the start has been wobblier than usual and it has yet to find its feet. From a 1000 point bank I am down around 400 points and (whether or not it is sound strategy) I have reduced my stakes to protect the bank.
I have yet to have a losing season following Football Betting Tipsters selections, so I am confident that the service will return to profitable ways and, as soon as it does, I will increase my stakes. On that note, despite the staking advice on the site (throughout the season stick to a fixed amount per point), I intend to use a rolling bank as that both protects the bank and takes advantage of winning runs.
