The Surgeon's Loop is often used to make a "Loop to Loop" connection or can also create a fixed loop that allows an artificial lure or fly to move naturally.
Scott Walker's Go-To Knot
It is hard to argue with Scott Walker's success rate. His knots are strong, his tackle is meticulously rigged and cared for and his boat is impeccable.
When Scott says something works, it is best to listen. You see, Scott doesn't take anyone's word for things that work. He begins a process of testing and retesting until he is satisfied. My experience with Scott is that his process takes alot longer than others and involves alot more testing.
When you get on Scott's boat, every rod looks exactly the same. Every leader is the same length and every knot is exactly the same. This is no accident nor is it an OCD Captain gone crazy. Scott has found precisely what works and replicates it every time.
His go-to knot for tying on a hook is the snell knot.
