Again, thanks for posting your observations and I am a big fan of the Flexshooter head for its utility, size, and function. I'm still trying to understand how you employ it for video or stills panning for WL with a center column. In all of the years I've been shooting, I've never had a center column tripod stable enough for those applications and they all flex or wobble. As much as I prefer my Flexshooter in place of a gimbal (size, compactness, ease of use, access to the entire camera) it is not as smooth or have the ROM of a gimbal. Nonetheless, it is still my first choice for travel mated to a bowl tripod.
Well, the simple answer is: I don't use it this way .
If I shoot landscape it is "normal" shooting of a scenario I like, i.e. single shots without a need for panning and stitching multiple images together, and video I don't do at all.
The primary application is for to replace my big tripod that I got for big 500mm / 700mm /850mm setups with something smaller, if I don't have planned, purely stationary shooting with the big e.g. from a tent with the big gun, but want to have full flexibility on hiking days with lighter lenses like the 180-600, so that If I have a situation where need something to provide support and working with the flexshooter as a gimbal replecent and when I am on my way between locations I can at the same time use it with the ballhead function when I find somethinig interesting for close-ups or even makro ... all on all the more spontaneous kind of "working".
Yes, if you fully extend this center column you get some swing, but the damping of the Carbon stuff is pretty good compared to e.g. a Manfrotto aluminium triod I used to have some years ago and If you shoot with an adequate delay and/or with a remote, it works fine for me, if the weather isn't against me. Normally a delay of 5 sec is enough to let the wobble calm down with a normal lens on the camera (i.e. 24-120, 105, 14-30 or such alike), IF the center column is required to be used. But because of the T at the end of the tripod's name it's already pretty tall, so in most situations of this type, the center column is down anyway.
One thing that definitely doesn't work well with this seput stretched to the max is working on windy days and - as I already siad - this ios denifitely nothing for hardcore landscapers with precision panning for panorama in mind.
