Re: 3 wt for blue gill
My Favorite rod is a 7'6" St. Croix Imperial which is old and labeled 2/3 for a weight.
Got it to fish small flies in tight places on smaller rivers and streams for trout almost always under 16".
This summer I was using it to throw up to #10 deer hair sliders and divers, #10 Bead chain clousers, clousers on a #8 9672 with 1/50 oz lead dumbbells (not much of a chuck-n-duck), etc.
The rod handled juvie large mouth, large crappie and the like without much of a problem
I'm currently out of my mind, but feel free to leave a message, and if you would like to reach me by phone, please hang up now.
