Jeff, Mike, thanks for the advice. I''ll try it this weekend.
[Note: One additional complication was that my first generation B&R
Rig placed the mast groove 14 inches above the boom (don''t ask why, I don''t know), causing the slugs to fall out as the main was lowered. In the future I might get some mast gates made and attached above the boom to effectively lower the groove, but for now I''ll try sticking a thumbscrew slug at the mast groove opening to keep the main slugs in the groove.]
