jfc,

Thanks for that, and you are correct about sportingbet they have a similar policy to centreracing.
This is the biggest problem facing people today that bet full time, it's alright for all the adds and spruking from a huge amount of corporate bookie sites, but there are very few that will keep you on if you constantly win.
The only one I have found is IAS whom I use for fixed odds ( when it is to my benefit).
I have taken a reasonable amount of money off them in the past couple of months with no problem at this stage.

All the best.
