Here is what I own: http://www.jobu-design.com/Jobu-Jr-3...-Kit_p_16.html
Here is the blurb from their site: "The Jr.3 Deluxe kit weighs in at 1.5 lbs, 680grams. This is the lightest, best functioning gimbal head on the market, capable of supporting and balancing a 500F4 and Pro body comfortably. Yes, we still recommend a bigger HD3 or Pro2 gimbal for daily use, but if weight is your primary concern and you are travelling by air extensively, then lighten your load: Get a Jr.3 Deluxe, your back will thank you."
Here is a link to me in the Falkalnds:

While rated for less weight, it worked fine for me over two weeks in on four different islands.
Going back to the OP's question, I was responding to that.
