The next time youre headed to Yellowstone to fish, you better make sure you have Loon Outdoors Deep Soft Weight in your bag. This charcoal-colored nontoxic (no lead), Tungsten-based product is one of the few sinkets allowed for use in the park. Just apply to your leader and cast with assurance your nymph will quickly find the bottom.
On hot days you can place the product container into the stream to "firm up" Deep Soft Weight to a desirable consistency. On cold days you can keep the container close to your body so it can remain pliable. Don't leave the product on your leader after you are through fishing as it can warm up and stain vests or other articles. Stays put best if placed over a knot. Select depth by positioning on your leader. Select size depending on current strength. Place in front of the fly so it acts as a bead head.
