Opinion needed from Bettingresource clients!

Are there any clients of bettingresource here at betfair? I have been an exclusive pinnacle user for bettingresource picks but I heard that the odds in betfair exchange are better for tennis and soccer.

If you are client of bettingresource, please let me know the following?

-Are you getting better odds than pinnacle (after deducting betfair commission) for the BR releases? Are you able to match the full amount that you want to bet at better than pinnacle odds?
- If so, how much is the margin in profit using betfair over pinnacle.

THanks.
