Re: hook size and hackle size
Flysean,
In most cases, the advice you have been given is correct. But in some cases it is not.
In fly tying proportion is very important. Consider the hook as the skeleton upon which the fly is built, so the components must be in proportion to the hook.
For a standard dry fly, the body, tail and wings are of the same length. Since the shank of the hook determines the body length, it also determines the length of the wings and the tails. Since the palmered hackle on a dry fly represents the wing, the hackle should also equal the length of the hook.
However, hooks are not sized by their length; they are sized by the gape (gap in the colonies), the distance between the shank and the barb. Fortunately, for most standard dry fly hooks, there is a fixed ratio between the hook gape and the shank length. The shank is 1.5 times the gape. So for a standard dry fly hook, the hackle should be 1.5 times the hook gap and this is the length they will send you.
However, in some cases the sizing does not work. For example, when tying very small flies in tiny hooks, the hooking gape is so small that the barb can sometimes miss the fish. So for small flies I use 2XS (2 extra short) hooks. A size 20 2XS hook would have the a shank length of a size 22 hook but the gape of a size 20 hook. In this case, I would use a size 22 hackle that matches the length of the hook shank even though the hook is a size 20.
Similarly, some dry fly patterns call for an extra long dry fly hook. Again the appropriate hackle size would not match the hook size for a 2XL (2 extra long) hook body.
So match the length of the hackle to the length of the hook and not the "size" of the hook. Sometimes the sizing of the hackle is off so alway check before you tie.
