I haven't quilted a big quilt on my Juki. Only lap and baby size quilts. I tried the supreme slider on my juki and I wasn't impressed at all. I think that doing a large quilt is tricky. You really have to manage the bulk so that there is no resistance. I do use goves. I just got a Sharon Schamberg Quilt halo, but I haven't tried it on my Juki yet.
