Was in a similar situation, with similar - maybe a little lighter - gear: 5DIII, 17-40, 70-200 F4IS (plus shorter primes). I wanted more of a balance between size, strength and weight, so I went with the RRS BH-40 and 24L. Perfect so far. What I didn't appreciate until I got it was that, even with the 4th leg section giving the 24L a good amount of height, with only the first three parts extended it's a very workable and usable height. Only minor complaint is that I would like the main switch on the ballhead a lot better if it was a round knob like on the BH-55 rather than the lever style - but like I said, minor.
I did consider the BH-55 and TVC-33 but wanted to go a little lighter. If you want strength only you can't beat that, or even the 34L and just don't extend the fourth leg section. You'll be set for life.
