I have made several of the Slumpbusters. I do not know what a NightAngler's Hibernator is, and I looked it up. Do you have a pic with a recipe? I have both pine squirrel and red squirrel. The pine squirrel I have does not have as long of hair as the red squirrel does. I also have black, but it is dyed, so I do not know which squirrel variety it came from. Squirrel makes good flies in my opinion.
