but what is the purpose of hooks with straight eyes vs. with down eyes? The TMC 100 and 101 hooks are the exact hook, but the eyes are different.
I know I prefer the down eyed hooks to tie flies because I can put head of the fly on the bent part next to the eye and it comes out nice and clean. But surely that can’t be the reason, can it?
Or does a down eye sit in the water differently than a straight eye.
Believe me, I won’t lose any sleep over this, I’m just curious. And if there is a reason for it, I would like to know.
I never believed the myth of the eye’s being straight or down affected the hook set. If you look at hard lures like the one’s that bass fishermen use, the eye’s are straight, or on a clasp of some kind if it’s a crank bait.
The only thing I could think of is it may sit the fly differently on the water, maybe letting it ride a little lower in the film or something.
I understand jig hook eyes being the way they are for nymphs, but I don’t tie those.
I agree that the hook shape is more important, and I personally like a dry fly hook with a wide gap.
Down-eyed hooks are easier to tie tippets onto if the fly is a parachute. I thought I read somewhere that the reason was that with the Turle knot (that used to be ubiquitous) a down-eyed hook was supposed to pull straight; whereas with a Turle knot and a straight-eyed hook it would pull at an undesirable angle.
