I do alot of live concert photography and am looking into getting a new flash with a great recycle time. I currently have the 420ex and the 580ex. I just use rechargeable AA batteries, but neither recycles at the rate I need them too. Especially when I am trying to use the burst mode, half the photos don't have a flash going off.
Any reccomendations on a good flash to get? Or any other suggestions at all? I currently shoot with a Digital Rebel, and a Canon T-2 film camera.
Thanks!
