I had been using Organ 90/14 with Connecting Threads Essential thread for a couple of years. Works just fine. Then I switched to a topstitch Superior titanium needle (100/16) to quilt my last quilt with Aurofil . I fell in love with both, and kept the 16 needle in, just because I didn't want to go to the bother of switching back. However, I don't see the need to go with the pricier needles on most of what I do. Just went to the 16 because I needed to quilt a very special quilt and thought I'd splurge. (It was worth it.)
