Q: 7. Will this work with a Pocketwizard TTL and a Profoto Air TTL remote with all it's TTL and HSS functions?

A: This will not work as TTL at all. Only straight hotshoe to fire whatever is sitting in either the 2 slots. As you can see there is no other TTL contacts on the hotshoe to talk to whatever is attached to it.I wanted to buy this as I wanted to use my Canon transmitter and a PW at the same time. Problem is they made the hotshoes too close together so it was way to tight. Additionally when I tried to trigger them both there were some problems firing to get both to work together.The most problematic was the Profoto Air TTL, it simply would not fire any of the strobes at all. I think the Air TTL is looking for the signal contacts from camera hotshoe and since there isn't any on this splitter, it doesn't want to fire.I also thought I could use this to fire my Canon transmitter AND the Profoto Air TTL together. Again it wouldnt' work and the hotshoes are too close together. I really think they need to go back to the drawing board and redo for people who use dual triggers to fire all their different strobes together.

Q: 8. Can the ball be rotated so that you have a vertical perspective as well as the horizontal?

A: Yes, the ball flips completely 90 degrees to the side. It will hold steady.Generally speaking if you use portrait mode a lot, you may want to get an L bracket. It's much easier to get all lined up when you can just put your camera on top already in portrait mode.
