I'm looking for another flash gun which will compliment my Yongnuo 568EX II and my Canon 430EX II. It will be used in the main for wedding photography. The YN686EX-RT looks a good bet but I own lots of rechargeable AA batteries so do I need yet another battery type in my bag? I've thought about Godox but will it work with my Yongnuo triggers which I use?
