My favorite bluegill rods are both 4 wts. The first is a 7'11" Orvis Superfine. It's light as a feather, has a nice slow action and will let me deliver a fly like a leaf falling on the water. Yet it has a surprising amount of power and will let me cast a 4 or 6 wooly bugger about as far as I can with one of my other rods. The other is an Orvis ZeroG. This rod is much stiffer and has a much faster action than the Superfine and lets me cast a bit futher and handles the wind a bit better. I can cast all day with either of these rods and not get tired.
