I use Connecting Threads polyester thread when quilting. My machine is a HQ16 and the polyester thread works wonderfully in it.
It's generally not linty, although I did have one spool that was linty. That was an exception, but I'm sure any kind/brand of thread has an exception now and then. I've never had a problem with it breaking.
Density of batting makes a difference, but I think it's more of a tension/speed issue than a thread issue. I frequently use fleece for batting because it is light in weight, yet warm, and allows a quilt to drape better than any batting I've tried. The light weight is especially important to me when making a small childs' quilt. The lighter the quilt the more likely the child is to drag it around and love it to tatters!
