So I've currently got a single 580EX II flash and the fact that my brother is getting married* in a few months has resulted in me being asked to do some photography at their event - so I'm using this as an excuse to upgrade my flash setup a bit.
The new 600EX RT flashes are ideal as they offer wireless control via radio without having to add something like Pocketwizards to the set up as well. So I'm already sold on that aspect of the system. However I'm wondering if the improved menu and thermal performance of the EXII is worth the jump in price over the original versions of those flashes.
My main areas of interest are action/wildlife/insect/macro photography so I'm wondering if a faster recycling speed offered would give a real world noticeable difference in performance for those kind of situations; or if the real world difference is really more marginal and not worth it.
I already use a Pixel battery pack** with my 580 and would plan to add another pixel for the second flash as well for, again, the improved recycling performance there.
So is it worth it or am I chasing tiny improvements that won't net me much if any real world difference in performance.
*I am aware that standard advice is to move house, change my name and deny any relation in a bid to escape this terrifying prospect.
I'll also note that I've a pair of modest softboxes and stands (have to borrow my sisters flash to use the second box) so I've some basic lighting that I can use to setup for a screen (which I've been assured they have).
**I also use it with my macro twinflash where it makes a massive difference to recycling speeds
