What good are economical hooks when you can only use 25% of them? My experiences are only for size 18, 20 and 22. Before you put these in the vise...make sure that the entire eye is there, some of mine are missing, some of them aren't even closed down so thread gets inside the eye. While in the vise, don't crimp the barb with the vise, they will break. While tying, watch your thread tension as something as tightening your whip finish down will snap the hook. While fishing, use only 7x tippet and fish only 4" trout as anything bigger will snap the hook.
