they are a microfiber i found in the fly tying dept. at Sportsmans Warehouse. they are called "Microfibetts" by L&L products. yeh, a lot more work but make nice looking fins and are tough. i cut slots into the bait before i paint it and epoxy them into place before i clearcoat it. i like the look better than the ziplock bag method, i think they look more realistic and don't offer as much resistance for the tail action.
Emmett, thanks for the paint tip, picked some up and will give it a try.
