I'll be the only wedding photog who stands across the road from the church, with a 300mm f/2.8 on a monopod, shouting, "No, closer. No, closer still. More. A little more....." 
Seriously, maybe the 15-85mm will have some use, though it's a bit slow, and the 70-200mm will be good for some candids, but I'm thinking I should hire a fast wide zoom. I'll be using a 7D, so maybe the EF-S17-55 f/2.8?
I've just bought a Nissin Di866 MKII (not delivered yet) which I'll have to practice with, coz I'm clueless with flash, except for rally cars in welsh forests at 2am - not the same thing really.
Boy, have I got some learning to do
