Another thing that has come up recently is that Organ needles are just slightly shorter than Schmetz. Organs work better on Janomes. So, the brand of needle and brand of sewing machine can come into play as well.
ditto -- my 6600 Janome came with Organ needles in it. They do seem to work better for me.
