The SID (yes, it’s named after that sloth in the animated film Ice Age) and the Unholy Diver are meant to dive upon each strip. They are of course both articulated, so there is some great tail movement and the fly sway to one side or the other after each strip. The difference between both flies start at the base. The Unholy Diver is tied onto the multiple shank configuration displayed earlier, while the SID is on a double hook setup. The next, and most important difference is the use of materials and how this difference highlight how new synthetics have moved this style of fishing forward. The SID is tied using rabbit strips and arctic fox. The Unholy diver is tied using waterproof craft fur. Both flies do have a base of chenille, used to prop up the other materials and help provide the illusion of bulk.
