I can't remember exactly which design, but we knew how many bobbins per numbr of sewouts it took-and we were changing the bobbins more often-I think we had figured it out to about 20% less thread per bobbin. Enough that being a damncheapyankee we decided to just use them for when needed. Yes, they work better if a design runs into a lot of breaks-the extra 'drag' of the magnetic core keeps them consistent-and you don't get the birds nest when the bobbin runs out...but it runs out with no warning-so you get a lot of loose sewing when you realize it! Have to keep an eye on the machine a little closer at the end of the bobbin. So it's really not 'cost'...pennies don't amount to much-it's just personal preference. Once we get down to the bottom of the regular bobbins and need to reorder-several boxes to go-we may decide to just go magnetic completely since we do no high volume work at all, and a box of bobbins lasts for months.
