I usually stick with natutal materials for wings and tails on streamers. However, their is a sale on all the synthetic materials at the shop I use. Does anyone have any suggestions? They have a pretty big selection and I have no idea where to start.

I'd like to use it for larger streamers imitating baitfish. Maybe for tails on popper paterns. Something that moves well in the water without having to work the fly much. Thanks for all the input guys.
