We found that the magnetic bobbins we tried definitely have a lot less thread 
on them, and fewer per box. 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.
