Have you watched the Youtube videos? For those who may not have seen them (as I hadn't), here are links:

I have a PE-770 but have not used it much yet. Honestly, just from the few minutes of video I watched, this is not a method I would like to use on my quilts; however, I have experience FMQing on my domestic machine and also on my midarm frame. Compared to those, this method looks like a lot more work to me because of the need to make templates and especially to hoop and unhoop over-and-over again. But, that's me. I can see how this method might be attractive to someone working on smaller size quilts since you can be doing something else while the machine is sewing.
