Shannon, I only use Organ needles, so I can't help too much. The 75/11 and 80/12 are sharp. 75/11BP is a ball. The BP designator stands for ball point. The 75/11 BPCS is a ball point cool sew, which is Teflon coated. I don't think Organ makes a medium ball. At least I've never seen one. As far as sewing on nylon, I use a ball to prevent the fabric from being cut or snagged. Hope this helps.
