Seems to have the shimmer of polar bear but not as slippery. Ties in a little more like buck tail. Should be great for saltwater patterns. May have to give it a spin as shoulder material for my intruders?Very nice Dane! This Silver Ant has become one of my favorites in the last year or so. I don't have any experience tying with mountain goat, but from the photo it looks very similar to Polar Bear.
