Man I wish I could be with you chasing the sardines. I haven't been there in decades. Cut my saltwater teeth out of Key West back in the late 60s.
Packing and stacking deer hair shouldn't be that tough. Use strong bulky thread, take two or three turns around the hair before you start to tighten it to flair it, and DON'T let go of the hair until it is flaring conciderably. True, the longer you hold the less it will spin, but get the nack first, worry about even spinning later. Good luck.
Lots of feathers,
