After looking at more videos, I am leaning towards the 3LT Jack. I think I just need to decide and order.

3LT has 8 kg verse 5 kg rating, higher height, Arca-Style plate, monopod, case, etc. The comment from the B&H rep was "The 3 Legged Thing is easier to use in my opinion as it was designed by Photographers, not engineers"

FYI on the 3LT, the plates will accept the BlackRapid FastenR-T1 camera screw.
