I've gotten back to this and managed to find the issue.
My rope endpoints objects were pinned of end particles of the rope of course, and since you can pin only on obi collider they had obi colliders on them that got included in obi sim. Even though they didn't touch visually, disabling particles to collide with endpoints remove all the tension and rope bend weirdness. You can set their colliders "phase" to 1 (from default 0), which is the same as particles, so they won't collide with particles but still act appropriately.
