I have a Janome 9400. I use a purple tip needle and single hole throat plate , gloves, and the blue dot bobbin case for fmq. I much prefer the gliding foot to the hopping foot. My machine has an fmq setting that automatically puts the foot at the correct height. I don’t know if your machine model does that. My Pfaff QE 4.0 that I used prior to my Janome had both gliding and hopping and I didn’t like the hopping foot.
I’m sure you know this, but it’s important that there is no pull on your quilt .
As Watson mentioned I think you get smooth curves with the gliding foot.
