the stabelest video's i ever seen on a 2 axis gimbals have come from a y6 shape. very little yaw wiggle if any at all, stable in wind..very good. only reason i see going with anything more is if your lifting more weight. one thing to be careful of is with the y6 there is an issue getting the props out of view when cam is level. you would need to push the cam forward more, hang it lower, tilt it lower, or use smaller props or longer lens.--something to consider.
