I just picked up an Induro CT314 tripod and BHL1 ball head during the recent Induro sale. I've been a Gitzo and Manfrotto/Bogen guy for 25 years, but this was a great deal so I thought I would try it when a friend gifted me a Pentax 67II and 3 lenses. The Pentax is a beast of a camera, and needs some stiff support to tame the mirror and shutter. On the other hand, you can see my Canon gear in my signature. I also often rent a 400mm f/2.8 for sports. This Induro setup is super stable and heavy duty enough to handle the 400mm/1D IV or gripped 5D III combination, as well as the Pentax with a 300mm lens. For lighter gear, like you're talking about with a 70-200 and gripped 5d or 7D, you could easily step down to the 200 series tripods and the 2 series ball heads. I've only had the Induro for a few weeks now, but would easily put it up against my old Gitzo and Manfrotto stuff. It's really good, and comes with carrying bag, spiked feet, and tool set.
I looked at the Sirui 3204 and K-40X combination because it was less money, but the deal on the Induro and the experience of a friend with Induro tipped the balance for me. That and everyone was out of K-40x ball heads at the time. I have no experience with Sirui, but it seems decent enough, when I've seen it around. The Induro stuff has always seemed a notch better in my unstudied estimation, though.
The Induro sale is over now, so the prices are not super screaming deals, but still are a lot better than Gitzo for comparable products.
I have to add, though, that I've never had a problem with my Gitzo Mountaineer, except that it is a smaller model not entirely suited to large combinations like a 400 f/2.8. I've had my little Manfrotto 190 series for almost 20 years too, but it is really only suitable for small camera/lens set ups. I'm an old infantry Marine, so I reckon my definition of what I'm willing to carry and call "light" is probably different from most. I think this new Induro setup of mine is eminently portable. But my definition of cumbersome involves 81mm mortar base plates and HE rounds. Most would probably consider the Induro overkill and cumbersome. Therefore, my rec for the next steps down their lines for adequate gear given your setup.
