why do i have to keep opting out of the beta site

same

Don't worry, soon you will not have to ask yourself the question anymore, when beta.betfair.com will become betfair.com

same here........... don't understand why they keep feeling the need to keep changing it!

I'm not at all an IT specialist, but i think pages under Betfair classic are to "heavy" , i was frequently having problems to loading pages. Beta pages are less beautiful, but "lighter" imo

does your cache get cleared every time you close your browser?  Every time I go on betfair it is already saved from previous sessions and I never see beta.
