and get a 5DmkII and a 24-70 F2.8 - now your kit is complete for parites. If you miss the wide like your 11mm gets you, get a 17-40 f4 later (or a 16-35 F2.8, which is like a 10mm on your 7D). You will also appreciate your 24 T/S lens more on Full-frame.
It's a shame to see good glass go to waste on a crop camera.
You will thank me later.
