You might want to consider this as an alternative to a padded case for your tripod: get yourself a length of plastic drain pipe to fit your tripod & some padding... I've used 5" black pipe & caps. Glue a bottom cap on the pipe, wrap your tripod in foam, or even a towel, and tape up the cap on the other end. This also works when you need to ship your tripod, or large rolled-up artwork.
