Thank you weezy rider, I don't like the thread cutter that's my Sapphire has, it doesn't leave a long enough tail and the top thread sometimes unthreads the needle. It gets hung up sometimes too.
For free motion quilting, I prefer the vertical bobbin, it just seems to make a prettier stitch. It took me a few quilts to get used to the way the Viking Sapphire does FMQ.
