SteadyShot modes for 200-600mm

[bguiliano]

Hi everyone, 

I have a Sony 200-600mm lens that I use a lot with my A7RV for shooting wildlife, mostly birds.

I shoot them mostly handheld and usually keep the lens on mode 3.

I was curious if that's what most other use or if I could benefit from a different mode ?

Thanks

Have same set up.  Does not address mode issue but I found it helpful.
