Which second speedlight should I buy?

[noble55]

Hi,

I'm trying to work out which speedlight to buy. I currently own a 430EX II and use this with a Pocket Wizard Flex TT5 and Mini TT1 to use off camera but I now need to buy a second speedlight and maybe in a few months I'll buy a third.

My question is do I buy:

- the new 600EX-RT to future proof my setup. Obviously with the 430EX II I know that the radio functionality won't work but hopefully the next speedlight I'd buy would be another 600EX-RT so it would make the setup more flexible. I'd also sell the Flex/Mini as the 600 would be my new Master.

- another 430EX II...if I do this do I have to buy another Flex TT5 to make them both talk to each other? If I do then it seems pointless to take this option but let me know.

- a used 530EX-II and again sell the Flex/Mini.

Any comments/advice would be much appreciated!

Thanks

Zoë

I sold all my old flashes and Cybersync triggers and purchased two 600EX-RT and an ST-ET-RT and have never looked back. I don't miss the triggers and the RT is great. Going to get a third 600 one day.
