A Drink or two sounds like the goUm, well if you can catch me first... the old carpet beater is what I used to get, not that I'm that bad, or, I can buy you a drink when we meet ?

Hooligan , does it turn you into a wild Lawless ManI stand behind what I say. I can offer up this (empty) but highly collectable souvenir for my being equally empty headed in my previous statement. Just the one, as the other I will save for myself.
Depends - I don´t have common needle bearings in there, but crowded, so this means about factor 2-3 higher load carrying. Same with camshafts running on crowded types. You could find lots of rockers with needle bearings in them, crowded in sports Earles BMWs like R 69 S and common types in later /5 or /6 types. So it is a matter of dimensions, not just rocking motions. Same applies to taper rollers in swing arms and all, not great but provided no grit or water gets in they last very long. Brinell effects are due to exceding load properties of that bearing, not from small rocking operation.
A bronce bush in the Vincent rocker might not last extremely long I´d think, just the total surface as a plain bearing is not really ample ?
I did a number crowded needle followers , in the Guzzi and three sets for prewar Horexes, original no bushes in them does not work long, too poor lubrication and only limited space for a lasting plain bearing type. You can find roller followers in modern cars too, or KTM. Just dimensions for the job have to be suitable, so no brinelling by rotation or just rocking.

I can follow your logic regarding the needles , the more of the crowd , the higher the tolerance to the load specially when dealing with a rocking motion . Are the details of your assembly of parts available for general release to the membership , if so would make interesting piece in MPHDepends - I don´t have common needle bearings in there, but crowded, so this means about factor 2-3 higher load carrying.
