Remember Organ makes different types of needles. You don't want the ball point for sewing cotton. Organ makes needles for Brother, Janome and Pfaff special just for those machines if you find your machine is fussy with the regular Organ needles.
I studied about steel production in a metallurgy class. Japanese steel is the best steel for needles and pins. And the Japanese manufactured needles are the industry standard for quality needles. I always look for made in Japan when buying pins and needles.
