There has been a lot going on and I have some catching up to do. Mark Morris at improve Photography did a very extensive ball head review https://improvephotography.com/46538/11-best-ball-heads-500/ And the winner is the Acratech GP Ballhead. Mark is taking the tripods and ball heads on the road so photographers can get some hands on time with a large assortment of tripods and tripod heads.
