Anybody use magna glide bobbins in their Juki 2000?
 

Was gifted by DH a Juki 2000Qi, i love it, i really really love it but the bobbins sure go fast. A blogger suggested I get some magna glide bobbins because they go so much farther. I assume I would get size L since my bobbins are L's. Anyone here had experience with this? If so can you choose cotton or which ones specifically do you buy, thanks for any help in advance!:D
