Hi Joe. So smart of you to do a test sandwich. It's much easier to fix pesky problems with that than once you're working on the quilt. Ask me how I know!
Two thoughts: I recently got that same SS WF for my 201 and it made a world of difference, so yeah you may have a lemon. It's worth talking Jennie about it. In addition, sometimes machines don't like polyester batting. It's slipperier than cotton batting and may lead to uneven feed. You may want to try another sandwich with a cotton batting, just to see.
As for the FM foot, personally I wouldn't go that way simply because FMQ requires practice to look good. I can't imagine that doing SITD or any straight line quilting would be easy with a darning foot. But then again, you may be a much better quilter than I am!
Good luck and keep us posted on your progress!
