I'm still very new to using a tripodhead with a tripod. I recently purchased a Benro Tripod with Tripodhead. How do you guys carry the tripodhead and tripod? Do you mount the tripod head with the tripod and leave it until you need it or do you keep both units seperate until needed? Do you carry the tripod with the tripodhead already attached or install the tripod head on-site? Thanks.
