So, my sister's wedding is this weekend, and to my own surprise I'll be shooting the first dance! 
(apparently the hired photographer doesn't want to stay long enough)
She already understands that I can't guarantee any results and any shot she gets from me is a bonus.
My available gear is 5DmkII, 600D (t3i), Speedlite 430, 50mm 1.2, 16-35 F2.8 (or Tamron 17-50) and 85mm F1.8.
I was thinking I'd put the 16-38-5 (or my tamron 17-50) on the 600D and use that with flash, and have the 50mm 1.2 on the 5DmkII. My reasoning being that I don't need the most light sensitive setup when I use flash, and if the available light allows it, the 5DII with 50mm might work. I want to take some shots with each setup so I have the best chance of getting a result that's good.
Does this sound like a good strategy?
Do you guys have any protips to share? (photography related, not family management related
)
I could get my hands on a remote trigger for the flash, but since I have limited experience and this is a one time only event, I don't feel comfortable using new techniques unless I really have to.
