Vision nano mono tip The material works best when you need to use small flies and delicate presentations. It has superior strength and is very easy to tie. It stretches more than other paw materials so it works as a shock absorber, a fantastic feature when using thin paws. Thanks to its extensibility, you can use thinner paws than before when the fish's hasty knuckles with the head are effectively absorbed by the material. Nano Mono, like all other vision paw material comes on a color -coded, interconnected and rotating coil.
