I wonder what the old version was like.
For me, the biggest thing is, while it's not necessarily meant to take large modifiers, I wish it did a better job of handling them for the times when it's just easier to use what's available. I think it could still use a bit more tension (or maybe have that part made of metal so I'm more comfortable torquing it down). That maybe would not be a complaint if there was a little more guidance on how large a modifier could realistically be used. Also, I wish the angle between the mount and the battery grip was a little bit larger.
Other than that, not bad!
