Ben,
I think that is right.
I have been reading your queries and they are really quite interesting. This material thing can really be confusing.
I have quite a bit of material in huge excess. Stuff happens over nearly 40 years of tying LOL.
You can PM me or I will give you my phone No. and feel free to call. I can put together a package of some pretty good stuff for you. that way you can get a chance to try out some small samples and determine what is appropriate for you and what you are playing with. I have some stuff that I couldn't use up in two life times!
My phone 206 433 8818. early evening is good say before 8 or earlier.
Or you can e-mail me at davesu@q.com
