Hi,
I have Babylock machines also and here's a hint for you when FMQ.
I unplug my foot pedal and set my speed control a bit more than half speed (about 3/4) and use the green on and off button when I quilt. That way I am not trying to keep the speed of my hands and my foot in sync....the machine goes at a consistent speed and I can control my hands better. I was always trying to move my quilt too fast I found out.
You should be able to quilt great on a Quilter's Choice...but you have to practice, practice, practice.
Good luck...that tip works good for me.
Bev
