I am a little late to this thread, but have read through most posts. I am new to LA and cannot imagine doing what you are doing on a domestic! Excellent FMQ!!!
My two cents....I think you should keep the same density quilting throughout. The vine design in the braided border does not seem to give it enough coverage.
The McTavishing swirl would give you the chance to do as much or as little as you want.
Be sure and post the final result!
