I use my APQS Lucey Long arm the most. But I have used my Bernina BSR on my ex 630. And recently, I have been thinking about maybe learning to use my Bernina's to do ruler work on smaller projects and did try it out. It is on my list, both ruler work and using my BSR again with the new Bernina's. Of course, I will do the big quilts on the Lucey.
