cool sean, good to have you in the swap. One thing to remember is that a big steelhead will often destroy a trout hook so you'll want to think about what hook you tie those caddis on. I'll put you on the list. D3, I've got some foam I'd be happy to send you, just PM me your address and I'll get it to you.
sean- take a look at a "crystal caddis" on google. or type in skater october caddis and you should come up with ideas. I;d tie your pattern on an up eye light wire hook. I use Daiichi for most of mine. But Gami makes a fine hook too.
I would love to do this swap but I really dont have the time. The skater I tie is brutal on time consumption. Wish I could. This is a great swap idea.
I tie on a thin piece of round plastic I pull from the corner of a hanger on top of the back of a size 4 or 6 which has been melted and shaped to a 45 degree bevel. You can just barely see the edge of it in front of the wing, sticking out in front of the eye. I color it black w/ a sharpie.
I lay down a base of thread, then i attach the plastic piece, then I cover the plastic front to back with thread. Hit it with Zap a Gap and let it dry. Then I start at the back and attach the wire followed by tying a dubbing loop and fill it with whatever color you want of dubbing and then wrap dubbing to the almost the eye, tie it off and then wind the wire to the eye and whip finish. Then continue with the dubbing loop to the front of the plastic leaving about 1/8"-3/16" for the wing and tie it on normal and then shape with some curved scissors.
The nicest thing about having a big plow on the front is it rides high and makes a beautiful wake even in really slow water conditions.
(edit) a tiny bevel on the back side towards the hook bend on the plastic makes it so you dont have to build up the ass as much with thread to make a smooth transition from hook to plastic.
The other nice thing about this design is unlike a riffle hitch which usually skates with the hook pointing sideways this always skates with the hook down so it improves hookups IMHO.
