I use a number 14 for FMQ on both my juki's. I have the 2010 on a frame and 98-TLQ for piecing. I used the 98 to do FMQ tabletop for 3 years just bought frame in July. Anyway I was having a lot of problems with thread shredding no matter whereI set the tension. I called the seller and he said "well are you using a 14 or 16 needle? He sent me a 14 and I've never had problems again.
