Just a follow up here. I got the new mast base. It has a place for the rotator arm, and the pulleys for the bottom of the downhaul as well as for the main halyard. Adding this can clean up a whole bunch of stuff. My current retrieval grommet is centered behind the tramp pocket - I'll use that for the rotator line and add a grommet a little to the left for the retrieval line. The only thing is that the new casting has two large holes underneath it. One would be for the Infusion internal diamond adjuster, not sure about the other. I'll have to seal those. Anybody actually ever pull the mast base off of one of these things?
