I'm a hiker and backpacker. I love my CT-3441S.
It folds down to nothing, weighs nearly that, and worked exceedingly well on my two romps through europe (italy and germany/swtizerland) paired with my 5D and 16-35II and 100L.
In fact, I'm leaving thursday for Greece/Croatia with the same kit.
I also use it with my 70-200 II on a gimbal and don't feel like I'm making any compromises on stability, but everyone has different needs or expectations with their gear.
It works for me and I love it. Didn't have to pay an arm and a leg, and didn't cost so much to make me feel like I have to baby it.
sure beats what i was using before lol
