State of Pennsylvania, these would not be legal in special regulation fly fishing trout waters. The state defines a “fly” allowing a combination of artificial and natural material, but not 100% artificial material construction. State uses the rule to minimize hardware throwers on their prime trout water. Should be OK on put and take waters in the state.
@@myrlstone8904 I was actually thinking of subbing out the tail for some hackle. Missouri's definition of a fly varies by conservation agent so it's always good to be on the safe side ha.
