Leland, mind sharing the when and how of fishing FAT? Do you fish them in summer because of their smaller yet fat profile, winter down deep, all of the above? I am printing your photo right now. Fat is good!
The Freight Train has been my favorite steelhead pattern ever since I first saw it. I have tied it in so many different permutations. (Randall Kaufmann had a good chuckle when I told him what I had been doing). I even tied five of them last night before I spoke at the Overlake FF Club meeting which they raffled away later in the evening.
My latest Freight Train is in my "Fat Family" of flies. The hooks are 1/0 Gammy "Split Shot Drop Shot." The size fly is #10. You gotta love tying big flies in miniature.
A few of my friends use them as a "closer" for summer steelhead. I use them all the time except when I go dry with Mike Sturza's Steelhead Muddler, which he ties on the same hook. In fact, the first time I saw the hook was at Mike's "Lost Creek Fly Shop" down in Onalaska.
As for winter fish, the jury is still out on the Fat Flies. I have been using the Fat Brat in low clear water when I'm the first through. I'll try to close with it the next time I get a pluck.
