I love to machine quilt but only go to my walking foot and straight line quilting if I absolutely have to. I find I'm more apt to have tucks and bunches, and it takes me a lot longer than free motion. I just finished a challenge quilt for my guild which was a modern strip quilt depicting a "bar code" so everything had to be straight line....I set it aside because I think I'm going to have to press out some of the "bunches" I made. I really hate to re-do something.
