Under 2.5 Goals Exit/Hedging Strategy?

[Guest WinLoseOrDraw]

I am having good success with backing under 2.5 goals of in play teams where no goals have been scored and the game has passed 30mins/at half time. Any suggestions for hedging/exit strategy? I have tried backing the under 3.5 or 4.5 goals market (prefer this one because sometimes there are freak scorelines) or you can also place a small over 2.5 goals bet around 60 minutes if no goals have been scored to get your money back. Of course it also helps if you only back 5% max of bank.
