Thanks for the feedback chaps. I see what you are both saying and appreciate your comments.
You both mention proportions, perhaps I should explain about pic/fly 1 and 2.
I have seen a fly on 'buzzflyfishing-Trout and Grayling Dries and Emergers for sale'. It is called Spot on Dun. If you do a search the post is on here. I really really like that fly, it is tied very short. I am trying (badly) to create something like that. Looks simple enough but I
still can't get the proportions anywhere near right. Looks like I'm going to have to buy a few
