I have to agree with this. I've had a 9960 for a about 18 months now and have done a couple of queen size quilts with heavy flannel backing on them on it and haven't had any problems with the feed dogs or straight line stitching.

I actually like it better than the $2900 machine I bought earlier this year. (I won't name this one as it's really a great machine. I'm just a lot more comfortable using my 9960.)
