[QUOTE=Peckish;8576177]I agree with the recommendation of using a size 16 or 18 for quilting. It has nothing to do with speed, and there is absolutely no reason why you shouldn't use that size on a DSM.
I was told to use only the High Speed HLx5 needles because they were less apt to break with the high speed. But if you don't go high speed I guess you wouldn't have to worry about it. I do a lot of straight line high speed stitching and don't want to chance a piece of a shattered needle flying out to hit me in the face or eye when I'm zipping along. The high speed needles are recommended in my manual as well. Safety first!
This is what I use:
