In another post here, Mr. rriver made a comment that got me thinking. He said fish in his location can't really distinguish a size 14 hook from a size 16 of a given pattern. Thus, he tend to tye flies of the same pattern at least 2 size apart, such as size 14 and 18. So fellow fly tyers, when you are tying a particular pattern, how many sizes of that pattern do you usually tye and generally how much difference in hook size is there between sizes?

I tend to tye 2 or 3 sizes of a pattern and have been tying them all 1 (even) hook size apart. For example, for BWO's, I tye 14, 16, 18. Perhaps I should be tying 16 and 20.

Comments please. Thanks.
