I needed to get some assistance for my XF100-400mm, and I found this
SevenOak CF Gimbal Head Adapter. It functions in much the same way as the Wimberly
Sidekick at about $100 less costly. It attaches to my ballhead tripod mount,
and works perfectly.

I find a rotating collar, works just fine for me.

I assume that you are referring to the lens collar + foot. If so that does
allow rotation from portrait and landscape orientation, as well as attachment
to a tripod, or monopod. However, a gimbal provides for smooth, effortless
movement in all axes in addition to the rotation around the lens collar. This
particular one provides all the support, and freedom of movement at a
reasonable price $130.95.
