Tough call. I own a 7D. I love it for outside, but it does suffer in low light.. You may want to look at the newer Tamron 24-70 f2.8 G2 model which is stabilized. Other than that would consider a 1.8 or even a 1.4 prime. Cheaper and possibly a tad sharper. I was having similar problems and just picked up a used 6D. Not yet put it through any major trials yet, but I think it will solve my low light problem. When the wallet recovers, will be looking for a 24-105 f/4 IS for the main lens.
I have a Canon 1DX Mk2 and I normally shoot with a Canon 24-70 f/2.8 II. The last time I was shooting I replaced the 24-70 with a Canon 24-105 f/4 to get some extra focal length. The 24-105 was soft compared to the 24-70. I promptly took the 24-105 off my 1DX mk2 and put it back on my 5D mk3 where it normally sits.
