Polyprop and similar flies

[Mike-Connor]

Mike,
I noticed the fly pattern made with green parachute cord. The steelheaders here, use that cord to make slinkys, which are used to sink their lures. Have you ever put shot in the cord, to sink the fly?

That is not the same thing. The cord used in these patterns is solid soft braided cord. You can?t place something in it like a tube. Although you can push things through it if you loosen the braid, ( a hook for instance, or various things lateral to the braid).

The cord you mention is not actually a cord, but a cylindrically woven braid with a hollow centre. This too can be used for various patterns, and one may then place things in the cylinder.
