I also FMQ on my regular machine. (I do meander, stipple, and free form designs.) I do have an Elna 7200 with an extra long harp, but I have also FMQ'd a queen size quilt on my other Elna with a standard size harp.
I don't roll my quilts, I "puddle" them under the needle. Also the single most important thing I do is to play music and sing or hum along to the tune. It just keeps me breathing (when we concentrate, we tend to hold our breath and when we do that, we tense up). Singing (or humming) just keeps me breathing and relaxed and really helps to keep my quilting smooth and flowing.
