Sorry for not posting for the last couple of days, didn't have a lot to say and have been moving house and suffering with the incompetence of BT re house moves...
In my outright tips, I took the unoriginal angle of backing Venus and Federer, and I'm sticking by them. The match prices are very close to how I marked them so I don't see any point in hedging (which should always be a value proposition), but that's an individual decision.
I rarely like to get involved in betting/trading on finals because the markets are usually correct and I prefer to watch and enjoy the great matches rather than fuss about my position. During last year's men's final, I just closed out at the end of the first set and sat back and watched one of the greatest matches of all time.
Good luck with your bets.
