what type of wet fly just a standard soft hackle? Perch eyes seem to work better for me in the winter tipped on a jigging spoon. Try a drop shot rig using an aberdeen hook and threading on a 3" berkly powerbait trout worm, let it hit bottom and just shake your slack line, leaving the sinker on the bottom the whole time. tying your hook 20 inches up from your sinker lets you super slowly dead fall the bait by letting some slack in your line, watching for the line to jump. 6 pound test braid to a micro swivel then mono or flouro helps tremendously at those depths.
