I have a Canon 550EX and I want a long duration, fast recycling, external power source. Should I go with one of the Canon battery packs; or with one of the compatible third party packs such as Quantum. And if the latter, which third party pack do you recommend? I will be doing action photography indoors (ball room dance photography). Thanks.
