From Keystone Fly Fishing
This fly is a spin off Blane Chockletts ever popular Game Changer. With the use of articulated fish spines, flies have been able to get more action than ever before. I took that, and turned it into a Musky sized deer hair meat. For that reason alone, it's called the Pants Changer; for when that 50 decides to do a boat-side eat on the 8! KFF Diapers not included (patent pending).
