My two cents...
I shoot with a Canon 70D and a 24-105L mainly because it's still has the L glass quality, but its pretty wide range. I really do like this set up. Having the 70D be good in low light and the 24-105 having a decent range of zoom, it lets me just "walk around" with that set up and not have to worry about carrying a large amount of equipment. I would say to always get EF lenses that way if you do go Full Frame, you don't have lenses that you cannot use. Just my opinion, good luck in your decision!
