Thanks Moeee and Mercurial - much appreciated.

Moeee - to be honest, I'm not a huge fan of tennis myself - women's or men's.

I ended up betting on the WTA because of the sports I tested on my computer model, women's tennis provided the best returns. I've also found it beneficial to specialise in one sport.

One thing with these tips is that they're only of any real value over the long-term. A 16-month history suggests the current 12-13% ROI is a realistic return so there's not much chance of being an 'overnight success'.

Good luck with the punt.
