They're a hoot! Such a blast with the long rod!
Was out again today and got a few more, biggest was around 35-36".
I use weighted streamers with a sink-tip line. Lead eyes and those Sculpin heads by Fishskullz work to get your fly to where the cats are. This time of year you have to put it in front of their face. As the water warms however, they'll chase your fly and crush it.
Biggest thing with these fish is you need good strong knots, 12lb+ tippet minimum, a stout rod, and a hook that is at least 2x strong and preferably one that has a wide gap. I like short shank hooks as well as they hold better.
