The Adams is in my opinion one of the best all round dry flies, I tend to tie the body with mole fur but any form of blue/grey dubbing can be used. Make sure that the proportion of the body and tail are correct as are the hackles with the hook gape.
The fly can be fished static or on a varied retrieve via a floating line. I have had lots of success fishing this fly on lakes via an intermediate line and stripping the fly very quickly under the water, takes from rainbow trout using this method can be very aggressive.
Take the winging material and tie in horizontally towards the hook eye, Now pull the wing vertical and secure with thread creating a small post, around which the hackle will be wound.
Wind the thread down the hookshank to the position opposite the barb, catching in a mixture of red game and grizzle hackle fibres as you go.
Take some natural mole fur and create a slim dubbing rope, create a small tapered body along the hook shank
Tie in one grizzle hackle and one red game hackle (Make sure these are tied in vertically), cover the tie in point and make a neat thorax of moles fur. Secure the thread at the eye.
Move the position of the hook into a downward facing position, holding the wing post make a few turns of the the grizzle hackle. Make sure the grizzle is wound from top to bottom. (This stops the hackle pulling out from the post after a few takes). Secure with thread at the eye, cut away the waste (The amount of balance between the grizzle and red game is a personal preference, I use 1/3 Grizzle to 2/3 Red Game - Works for me)
Holding the wing post make a few turns of the the red game hackle. Make sure the red game is wound from top to bottom. (This stops the hackle pulling out from the post after a few takes). Secure with thread, cut away the waste (Use twice as much winding as that used for the grizzle hackle)
Trim the height of the wing post
Create a neat head, whip finish and varnish
