Wouter ,
That was basically what I had in mind for tramp rotation systems but with the sheave at the bottom of the mast included.
Also considering an exit block in the boom with light shock
cord inside to pull in the extra line. Probably not needed but would look very neat.
The Infusion looks like a bit of a mess.

Regards,
Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
