Poly Leaders

[stonefishin]

Has anyone used these? Apparently they come in different sink rates, but I'm not exactly sure how they're used. Do you tie tippet to them? Do they get used up eventually? Are they any good at all? I'm always looking for alternatives to weight on my leader or sinking tip lines.

They work pretty well. You just add straight tippet up to the length of the polyleader. They eventually wear out, but last a long time. I use them as I would a braided leader, but they won't spray water and use the sinking ones instead of a sink tip or adding extra lead.
