I have done 14-way out of a PAC. We found that any more than 5 (including camera) outside the plane was unreasonable and led to problems keeping the plane flying right. It isn't super fun being a diver either. I don't think I would be comfortable doing anything larger than 14-way RW from a PAC and 12 is a MUCH more reasonable number.
