I have a dubbing loop spinner but I don't like it. Here it is.
It drops the loop if you aren't careful when winding around the hook and it's awkward to use. I saw one in the Orvis fly tying manual that has two separate hooks that held the loop, when you twisted the loop, they come together. I kind of like the looks of that.
I'd like to see what you guys recommend. I've seen the brush makers with the plexiglass clamp but I think that's a little over engineered for me. I'd like to keep it simple.
