SLIP N’ SLIDE

The slip n’ slide is similar to the slippery devil. The difference being a synthetic tail on the SnS. This gives it a larger profile in the water. It takes slightly more effort to cast and retrieve than the slippery devil due to the larger tail. A variety of retrieves will work, and I recommend putting good energy into the fly to overcome the drag a larger tail can create.
