Never fished plain marabou jigs for browns but size and colour seem prefect! My first brown on a jig fell for a brown marabou spinner pretty much the same size which was inspired by the march showcase. This reminds me of a saltwater flyfisher that when he finally got permisson to fish in a stream, he caught 2 out of 4 twenty-inchers that were taken on opening day. He simply found himself the deepest pool around and chucked large, heaviely weighted wooly buggers into them, like he had learned to do in the baltic.
@stump: I do most of my brown trout fishing in a kayak on the baltic sea. 1/8th to 1/4th baitfish boolies like the one in my avatar work very well there. I troll them with the rod in my hand, giving them some action.
You may not always reach down to where they feed, but they will rise up to warmer water layers that help them digest their prey. You´d be surprised how many rods on those trolling boats are running sideplaner rigs a few feet below the surface.
Also, there are very interesting trends implementing
speed jigging techniques for large browns on the great lakes and the finger lakes. Ahh, and then there is mooching, and my personal favorite,
modified jet divers... A jet diver #20 will reach 40`on thin superbraid no props. Wich will usually do the trick, since browns have an open air sack. That means that for a decent offering, they will rise vast distances in the water column. The Britisch fish for their
ferox with large nothern pike size baits, and they don´t know
what a downrigger is. Sorry for the OT, but when it comes to large browns...
