This is what I wanted to hear. Of course any tripod maker will tell you how they would like for you to take care of their product, the question is how fragile it really is.
I don't abuse my tripod, but it has fallen a few times, and gets jostled in the back of my covered pickup bed, and has been in water and so on.
On my last trip, we had to lower our packs over a cliff on a rope. My tripod was well protected behind my tent that was strapped to the side of my pack, but my buddy wasn't so lucky. His pack slid down the first part of the cliff with all 90lbs of pack grinding his RRS carbon fiber tripod into the sandstone. It has a few scrapes on it now, but nothing more than cosmetic damage. Carbon fiber is very strong. The only real weakness to CF is extreme cold. We're talking conditions that are so cold that you might not be shooting in them anyway. Under such conditions, the glue that holds each leg into the metal socket becomes brittle.
what do you consider extreme cold and was there a failure?
the adhesives today that are available take considerable low temperature. and I do mean low. these adhesive have been around for quite some time in aerospace and are no longer considered "exotic" in nature or pricing.
these adhesives are used regularly at high altitude 36k-42k ft and at temperatures in the -45f to -65f range
One of the tubes on my 2530 has weakened up top where there is some play, but that's not the result of cold temperature --- it probably just wasn't glued as well as it should have been from the get go. I haven't had it fixed yet, but will have to do so at some point.
On the note of cold though... it seems like once you get well below freezing it's more common for the glue joints up top to become weak -- especially if the tripod is placed in deeper snow which causes the legs to become stressed. I haven't had this happen to me, but it has been an issue for many people. I don't know how the RRS tripods fare and if their glue is any better, but I'm definitely aware of the issue with Gitzo CF tripods in these situations.
that does seem to be a methodology issue on the part of gitzo and I am aware of it. maybe they might have it worked out in the new series? I have used my RRS legs in well below freezing and unfortunately below that magic 0F mark too. New England has a special kind of cold, believe me.
CF itself big issue is with high temps.
