200 Ft Suspension bridge -crazy rope issue

[Ascensi]

Hi I'm having an issue with the rope colliders not being an equal distance from each other and it seems to cause jitters- how can I make them equal? I have the rope set to .04 thickness,  0.351 resolution and 5000 particles... the bridge is approximately 200 feet long.
I've also added tether constraints because the rope would just keep stretching but also how the bridge sections are currently hanging doesn't seem natural/fluid yet maybe reduce the stiffness?

I have a video example but don't want to post it here.

Thanks, Kurt.
