4:1 mast climber

[Brion Toss]

Hello,
You can get ratcheting fiddle blocks, and one of those, combined with your current Sw/B, would give you 4:1. But as someone who will be turning 65 in, um, three days, I would like to suggest that you can slow down strength loss, and even increase strength, even in your dotage. All it takes is some brief, regular gym time, and persistence.
Fair leads,
Brion Toss
