I recently was having a problem with DSM quilting on a quilt with some pieces backed with featherweight fusible. I tried a Schmetz 75/11 microtex needle and found that the tiny "popping" sound I was hearing stopped while using this needle. Was using Mettler 40wt. cotton top thread/Mettler 50 wt. cotton bobbin thread.
I've been converting to the titanium needles, too, and really like them. But I managed to get a burr on this last one, to my great annoyance, and now have to buy more!
