I've decided on the Hensel L1200. At first, I was leaning towards the Profoto Acuteb2 lithium because of it's weight, but realizing that it might be more useful to have (2) 1200 w/s lights, with not too much additional weight gain. Another major consideration was the wireless controller. Hensel allows the use of the Profoto Air, which I own, and the range is almost a thousand feet! Profoto and Hensel do seem hard to find though, while checking the big photo suppliers, one minute it's in stock refresh the page it's not! Hensel also allows it to be used as a studio unit with the AC adapter, so no need for a second unit.
