I can't seem to tune the arm up perfectly. The arm section closest to the gimbal pretty much remains horizontal until the other section (closest to my body) gets close to its vertical limit. I am currently using two blacks throughout the entire arm. I have interchanged all of my 4 black springs and the sections still don't follow one another as they should. I spent a few hours today playing with tension in each bone and can't seem to get it figured out. I tried 4 blues and the arm sections seemed to follow each other nicely. With all this in mind the arm still booms smoothly and isolates my movements perfectly. I'm just missing a bit of finesse with the bones moving together and not having one hit its bumpers while the other still has a bit to go.

I'm also curious if anyone has ever had to replace or purchase another spring after one went down or wore out?

Yeah those Pro Arms are renowned for being really bad.....I'll give you £50 for it, or a straight trade for my G50.

I'll keep these two generous offers in mind.

I was looking a little closer at the arm and how it moves. One little thing I did notice, could be nothing, is the gimbal arm section comes to a stop before it hits the rubber bumpers.

First off. The springs will not wear out.

You have the tensions set incorrectly, wind them out to zero, then start to add lift until the arm is just below level on both sections. at that point both arms should track just fine.
