>>1098691>pubes dont flare like deer hair under thread pressure, the best it could be is pubes as a tail.While that is true it is not the reason why pubes would be bad for a popper. Deer hair contains a lot of air in little holes making it buoyant which is why it is used a lot for topwater lures like poppers.
Also the way it flares (new word in my vocabulary) makes it suitable for trimming to all sorts of funky shapes (see pic). Was mainly an issue before the advent of foam heads I suppose but it sure as hell is prettier than a foam head.
