Need opinions on next lens to buy

[Rocco]

If it's primarily for Weddings and similar events I would strongly suggest you at least look at selling the 17-55mm and buying the 24-70mm f/2.8L especially on a full frame camera it is a very nice all around lens and it will fit in with your current list of lenses very well too.

I don't understand that. He plans on going to ff, but not until next year. Replacing the already excellent 17-55 will cost him another 1k but won't help him with his original question.
After he moves to ff, absolutely. It'd be a great choice.

I had used my 100mm macro L at a few weddings and it did fine. For what it's worth, I also rented the 85 1.2 for a wedding and recently sold my macro to help fund my very own 851.2. That's my recommendation, because that's what I ended up going with. If you can afford it, buying the 85 for indoor stuff while keeping the 70-300 for a versatile zoom might not be a bad call.

That's what I meant ... with a full frame camera I think the 24-70mm f/2.8L and the 70-200mm f/2.8L would be great for weddings but for wildlife alot more focal length would be needed on a full frame camera. If he kept the 7D he could possibly get by using teleconverters on the 70-200 for wildlife.
