I've been using a Gitzo 1325 for the past eight years in the toughest conditions the Dakotas can throw at it. I photo almost exclusively outdoors, and at night. I shoot in the rain, but really love shooting in blizzards! I've used the Gitzo CF in temps down to 38F below zero. Nothing seems to affect it.
