What should i bet on?

It's in an old skybet account that i'd completely forgotten about and not used for a couple of years. I just checked an old email account and there's a message from them saying they've tried to pay me my dosh and close the account but the bank details they've got aren't working and unless i use it or contact them with up-to-date info within the next few days, they're gonna close my account anyways! F*ckers!

So...i'm going to whack 5.1 big ones on something and hopefully obtain financial security in the process.

WHAT SHOULD I BET ON? go.
