Halyard stopper? What's that? Haha, no really what's that? Stopper balls? Or jammers?
You're right though 3/8ths is almost too small for my winches. So smaller is pretty unlikely. But bigger might be nice, particularly if it becomes necessary to run the taper of a core to core eye splice. The 3/8ths sta-set I have for my spin halyard is almost too small at ~5000 lbs break strength. I really like to make sure my lifting rigging is sufficient for climbing standards. I guess my question is, is there any disadvantage to running smaller line in a big sheave.
