Oranges to Apples - Comparing ProVid and A-30 Arms

Hi All. Thought I'd open up the conversation I'm having in my head to the community to help me get some clarity.

I have rig that uses a ProVid arm. This is the arm with two sprung sections. It was recently serviced by Robert Luna in LA and seems to be fine, technically. A little harder to handle than the arm which I trained on which is the A-30. The ProVid arm was tuned lighter and confirmed to carry between 20-33lbs, and the A-30 guidance is not to exceed 30lbs. So we're pretty evenly matched in terms of capacity.

Today I prepped for a shoot tomorrow with a sled and camera package weighing in at 23lbs and swapped socket blocks to use the director's own A-30 arm, just to compare again. Why does it feel like the A-30 arm is so much more responsive than the ProVid? I'm fully open to any wisdom to point me in the right direction on all fronts. Technically why is there such an extreme difference in float / feel? How to improve my ProVid or just save up for a better / newer arm?

Thanks in advance!
