You probably realise this but you will get a more comfortable ride if you fully support the rear of the seat. The point on the RFM that supports the friction dampers you show does move up and down.
how about needle rollers in leu of ? Just the rollers and a little litheum grease to hold them in place prior to fitting ?Wouldn`t it be possible to use a closed ballbearing in this place?
I agree I sometimes think I am the only one who mourned the end of the Friction free Nylon FF6 bushes I thought they were a great improvement -the first batches were great I think somehow perhaps the last batch was in the wrong material ( thats the problem with clever plastic its difficult to quality test the finished item ) and then it was a case of give a dog a bad name...With that type of bearings there is ALWAYS the trouble of keeping out water or dirt. Most bearings die due to corrosion or dirt, not from overload. For a not very critical place I´d go for some low wearing plastic material. A little bit of friction in there is of no consequence, even with a hydraulic damper - which in almost all type has a LOT of friction anyway so no factor with that tiny amount of friction from modern plastics.

As I will use the already damped Thornton coil over suspensions, I had some Teflon bushes turned by my local machine shop to be used instead of the friction material.
They made them a tight fit on the stay and free on the internal small plates diameter, but I asked them to turn the outside a bit more, and now they slide on both side but still a snug fit.
Not sure which exact kind of Teflon they used.
