All valid comments, I thank you for them.
I agree that I should learn to modulate tension better, and hopefully will over time, but I tried a few spools of both uni and utc thread and found that I just kept snapping them, especially the thinner gauges. It was driving me nuts and so I just gave up on them (for now, at least, maybe I’ll try them again at some point).
So I bought black and chartreuse spools of Veevus gsp - expensive - and found that even with the slipperiness I liked them much better. So then I bought a bunch of more reasonably priced colored gsp thread on sale from fishon that seems at least as strong as the Veevus.
My loon tool-kit semi-serrated scissors cut gsp cleanly, but so too do my old $4 Rapala serrated braid cutters, though with less precision of course. As the Rapala cutters were never dulled by snipping all of my braided spinning line, I doubt superfine gsp will ever dull them either, and so I use them for all less precise cuts.
I picked up a pair of rite ceramic bobbins on clearance and they’re very nice, and also a pair of aventik ceramic bobbins off the ‘bay for $11 that work nearly as well: The tension adjustment isn’t as precise or smooth, but a tiny bit of grease on the disks cured most of the roughness, and a dremel on the detents will cure the precision if I decide it’s worth the bother. All tolled, even mucking around with more thread and thread related tools than I need, the investment hasn’t really been all that much.
Now I just need more practice. My six-week beginner class with Mainline fly tiers starts Wednesday. 👍
I’m definitely still a beginner, and so my product mentions should be taken with tablespoons of salt, but here are links to the fishon gsp thread, rapala cutters, and aventik bobbins for anyone interested:
