Boom preventer: Antal low-friction ring vs turning block opinions?

[benz]

Hi John,

Antal rings are great for any application where you're not heaving lots of line though under load: I'd not use one for a mainhalyard, for instance. But for your purposes, they're perfect. I run my Stay'sl and jib sheets through Antal rings rather than blocks, and it works perfect (high load/short run).
