so I want to know what is the right adjustment balance for a dual arm spring setup? Where should it stop at when I mount the sled on it?
You need a good dose of Peter Abraham and his workshop, LOL . . . . . but until then If I am getting what your saying . . . .
You have a two elbow arm and where should the rig be once you have the weight of the camera on it? Correct ?
I fly mine Neutral . . . .so that both elbows are horozontal . . . .LOL . . .
Hope that helps , There's definitely more to it, but I'm sure you know that, but that's the quick simple answer
Remember . . . . .Peter Abraham . . . .Workshop . . .

More importantly, the shot itself dictates how the arm links should be adjusted. For instance, if you are always working near the top of the range, you might adjust the arm higher than normal - with consequences for booming to the opposite end of the range.
In all cases, you want both arm sections to work together, so balance the forearm section (closest to the sled) first, and balance the upper (other) section to track with the forearm section as you boom fully up and down.
Posture affects arm performance as well. So does using a "back mounted" vest. Workshop workshop workshop. No simple answers.

If they don't track together, there will be a bump somewhere in the middle of the travel - not a good thing.
I suggest you START with both arm sections slightly DOWN from horizontal IF it is a 3a type /3 spring arm. Slightly UP from horizontal if it is a MasterSeries, Flyer, Ultra, or G-series arm. PRO? not sure - and I'd like to know.
Again, the shot itself should determine how the arm is tuned.
