This little bait fish swims suspends and catches fish. My family has been tying a variation of this fly for over 20 years and this little guy at just over 2 inches really will catch anything on the bank. We have had days were crappy loved it small loved it and striper love it. The wool design allows for free body movement with enough rigidity to keep it all together.
Tip: always carry Velcro in your box and if your wool baitfish gets a little bent out of shape use it to pull him back in. We use tough wool so brush hard.
