I also have a NOLTING PRO 24 w/ 12' table. Intelistitch is the only whistle that came with the machine. I love this machine. Getting started was not an easy task but the company was there all the way with me. My dealer is terrific too.
All my stitching is Free motion. This machine is wonderful to use. Smooth. Even the sound is cool. Like a muscle car of the quilting industry.
I can't even begin to count how many quilts I have done.
I do not quilt professionally. I just love to quilt.
peace
