I'd likely braid the bass too. Then I'd listen to the result and decide on the next step. If a next step was necessary, I wouldn't expect any unusual noises from the back scale in the top two sections unless there is some bearing or plate clearance problem. I don't know what bearing angles there are across the first and second counter bearing bars, but you said both sections are making noise. I assume they are fairly low. The best benefit from the least effort, with the lowest penalty should come from braiding or otherwise muting that 50mm second section. Remaining noises from the first front duplex should be comparatively minimal then, even with the low angle capo deflection. If not, you're now in familiar tuned front duplex territory. If I was rebuilding it, I'd want to increase the bearing angle, decreasing the front duplex length if possible depending on where that leaves the string height and angle to the pins. I can't say if this qualifies as an answer, but this is how I'd approach it as a work around. Ron N
