Has anybody in the good old US of A developed a printed, available,
specification for the pay-on gear for Dyneema etc. rope – like low
weight (aluminum? - note USA spelling!) rollers, low friction and low
inertia bearings, anything special needed for the drum , etc.?

I suspect that there is scope for saving inventing too many wheels
twice over.

(And for the avoidance of doubt, I am NOT going to get into the Bildan/
DC/DJ etc. spats – you are all welcome to keep those among
yourselves.)
