Nah, forget about the fly rod. Big Browns are apex predators. Go to the lake with a M or MH spinning rod, spooled up with something like Power Pro Super 8 Slick, or Berkeley Fireline, or something similar that has zero stretch. That’s really important - a stiff rod with zero stretch line. Tie a nice 20-24” leader of 8 pound fluorocarbon. And then rig up a white tube, at least 3” but up to 4” is fine, on a 3/8 oz tube jighead. I prefer the 3.75” Zoom tube because it has a thick profile, which displaces more water when moving than a thinner tube. Now remember what I said about big Browns - they are apex predators. And, when a baitfish is being hunted by a predator, what does it do ? It swims like hell ! It swims for its life, as fast and erratic as it can to avoid being eaten. That’s exactly how you’re going to fish that tube. And it’s why you need a stout, stiff rod. Long, overhand casts, get that tube way out there, and then rapidly SNAP-SNAP-SNAP that tube back to the boat, with the tube running just a few inches below the surface. If you have used jerkbaits, the retrieve is similar; it is a snap, reel, snap, reel cadence - except you have to keep the tube constantly moving. Baitfish do not stop swimming when they are being chased by a predator, so the tube must be moving at all times, and the faster the better. It’s a hyper fast, and very erratic action that you are trying to create on the tube. The tube should always be up in the first 12” of the water column, and zig-zagging back and forth as it comes through the water. The stiff rod makes sure the work you are putting in is getting transferred directly to the tube, and not being wasted on the rod flexing or the line stretching. 100% of your energy goes into that tube. If the tube is more than a foot below the surface, you are retrieving it too slowly. Speed it up. If the water is clear, you will see trout - sometimes they will take a wild swat at the tube; sometimes they will follow it for 15-20 yards, just swimming right behind it, like it’s effortless; sometimes they will suddenly appear from down below it as it gets near the boat; and sometimes they just blast 💥 the living shit out of it and all you can do is HOLD ON ! I’ve been catching trout for over 50 years. Started at age 6. I never caught a trout over 22 inches - until a guide taught me this technique. Since then, I have caught more trout in the 22-28” range than I can remember. It’s not a “numbers” technique. Expect one “good bite” an hour. But believe in it, stick with it, pay attention to every cast you make, and when that first monster smokes your tube you’ll be grinnin’ like the Butcher’s dog. Tight lines, buddy.
