I use some SITD on every quilt. I use my walking foot or do SITD free motion. Unless I am making a baby quilt or a quilt for someone in a nursing home, I usually use Aurifil monofilament thread ( nylon) with Aurifil cotton thread in the bobbin. I have never had a problem with it and have used different sized needles. I do start in the middle of the quilt. When I am a better quilter, I'll probably switch to quilting with cotton thread; but for now, monofilament works for me.
