Well, I figured it out. Basically the entire problem was the hairspring not being strong enough. To fix it, in Simplify3D I scaled the Z axis to 200% to make the spring portion twice as thick. Then I had it stop printing 50% of the way through, so that the overall part wouldn't be any bigger. Once I did that, it stopped being finicky and just worked.
