No argument here either! Excellent solution too & certainly inexpensive!
We're both thinking in the same terms, buy the better tool.
My question was only stemming from experience with beads that were not very good quality. I figured you might have a better handle on a particular brand or supplier.
I'm sure they vary a great deal.
Some of my older bobbins were damaged so badly that they didn't even work well for wire, at least not lead wire. I don't even use a bobbin for wire now.
When I tying commercially, I got into the habit of measuring & cutting the lead wire into lengths so I could duplicate the added weight each time I tied a particular pattern, and I kept notes about each pattern.
I gave the Tiemco ceramic tube bobbins a try, but didn't like them. Personal preference, nothing more. All the ones I use now are Griffin with the insert in the tube. A lot of the tying I do is with the Griffin Rod Wrapping bobbin, which is made to hold a 1 oz spool, and Danville Flat Nylon, my favorite tying thread, is available in 1 oz spools.
