I’ve had the FSB-6 with single lever release and carbon legs for a year or two now, and I love it. I’ve used it repeatedly in temperatures approaching -20F, the only situation I can think of where carbon might have a durability problem, and never had an issue. It does come with a padded bag for protection in transit.
I’ve had the same great performance in subzero temperatures with my Manfrotto/Bogen still camera tripod. I also ride a carbon mountain bike and have replaced lots of parts on my motorcycles with carbon fiber bits – also without incident 🙂 I’m not riding them in the subzeros, but I’ve had some stuff get bonked, a couple of times at over 150 mph.
The FSB-6 head is by far the smoothest, nicest feeling head I’ve tried in this price range. Period. In fact, I have been planning to order a second one for a while now. Before I bought it I read every review I could hunt down, no matter how obscure. I was very pleased with the result when I received mine, and would hands-down recommend it to anyone looking for a tripod in the $1500 range.
One thing about carbon is that it’s very solid. It also doesn’t transfer heat/cold as well as metal, which can make it easier to grab and/or carry during temperature extremes. As far as aluminum bending…well, I’ve bent lots of aluminum, sometimes on purpose. It only likes to bend ONCE. That second time, especially if you’re trying to straighten it, is a gamble.
