Hi,
I'd ask one more thing to those using carbon fiber tripods.
This is my first CF tripod, it seems very sturdy but I'm sure I have to care it more, it won't bear hits and mechanical strain as an aluminium one.
Do you use any padding or leg warmer to protect it?
I bought legs padding for my Manfrotto 055 from Manfrotto. My aged and loved Velbon now many years old has foam on all legs. They are still in good shape with only a few nicks in them,but they are not showing their age otherwise. Many CF ones only seem to have this on one leg now or none at all.
