I must have 30 bobbins around here. I have used many of them over the years. I used the old red plastic ones for many years and ones made by Herters to. I still have several of the Matarelli's around here. But they get a grove in them after you tie with them awhile.
When Tiemco came out with there ceramic bobbins I bought a dozen of them and still have all of them but one. That one turned up missing at a show I did many years ago. I have one of them that is getting rough around the mouth but I do not know if they will take it back or not as the company has sold?

I have to say when I get use to something I just stay with it. They get to be like old friends when you use them as much as I do.

I also have a Nor Bobbin that I have to send in and get fixed. I have not learned to use it yet but plan on trying to see how it works? The arms are lose in there sockets. I also have a Nor vise that I like for spinning things like streamer bodys and such. Good vise. Ron
