Tennessee,

Good question to which there may not be a correct answer. By that I mean, there are usually several differences of opinion about the angle of the eye. Some say that a turned down (td) eye has a better angle for hooking. Others might say the turned up (tu) or straight eye increases the gap space, especially in tiny hooks, allowing for better hooking.

I know that's not much help.

Here's another question: Are there any advantages of a tapered eye over a ball eye?
