Tying threads

[Skip48]

I just got some thread from a local dealer, it says its 3/0. Seems to me its just like some other 6/0 I have(Danville) . This 3/0 stuff has no brand marked on it, so I really don't
know who makes it. Thing is, I was under the impression all along that 3/0 is heavier thread than 6/0. Do I have that backwards?? This 3/0 breaks way easy. I was just tyin up some size 18 midges, and the stuff just kept breakin over and over. at first I thought it was a burr on my bobbin or something, but that ain't it. Maybe it's just lame thread?

Next question.....Kevlar thread? what's it got to offer for strengths and weaknesses?
I just got some killer yellow, green,red, & brown deer hair to do a bunch of poppers, and I'm lookin' for good strong thread.

Then..how about silk? seems like I used it way back years ago a time or two, but I don't remember much about it. I've been using Danville nylon for years now.

First 3/0 should be larger than 6/0.

Sometimes I use some mono thread and it seems to be pretty good, but I really have not used it enough to know what I am talking about.

I really like 140 denier waxed UTC (I don't even know what UTC stands for though), but mostly use Danville 6/0 on flies and 210 denier on jigs since large thread on jigs is fine.

Looked it up and UTC is Ultra Thread.

Kevlar is strong for sure, but since I have never tried it someone else should be more helpful on that.

Hope this helps,
