I've used several tripods over the years. Now, I only use the Leofoto SO 322C. This is an inverted tripod with a leveling head. I have used several attachments on the leveling head, but found the arca rail or a large bag works best. I really like the leveling head, but most of all I like the easy and fast adjustable legs. I use it for sitting as well standing.
When doing load development, I work from the bench and then fine tune the load on the tripod.
