Are you going to get an ST-E3? Or just run with the 3 x 600's?
Right now I use 3x600's. Eventually I will pick up a 4th as a backup but it will most likely stay in my bag. Not sure the exact numbers but the ST-E3 is a little more then half the cost of a 600EX-RT. So for about 40-45% off the cost of a 600 you get triggering capability but no flash, no AF assist, no backup, etc. Personally, i'll happily spend the extra as I view it as a value at that point. Why not sell your 580 to help fund your second 600 and then build on that in the future? Just a thought.
I just did my first wedding with the 600's instead of the 580's + RP's. I was hesitant about what I had spent to upgrade but I loved it. Controlling the off camera flashes was so easy and simple and I didn't have to worry about triggers. The RP's mount with a little foam O-ring on your slaves that seems to slide a little even without touching the flashes over time. Once the O-ring blocks the sensor I would have to take the flash off the stand, unmount the 580, move the foam O-ring, remount, put back on the stand. For me personally, in the middle of a reception, that was very frustrating. Now I throw them up on stands and they just work. I really found it useful using the ETTL on my on camera flash and the manual on my off-camera flashes. I think that only works with the 5D mark III or 1DX though. Hope this helps.
5D mark III x2, 5D mark II, 35 Sigma F1.4, 50L, 85L, 16-35L II, 24-70L II, 70-200 2.8L IS II, 100 f/2.8 macro, and not enough lights.
