A hens' mouth 'hinge' is in front of the eye, if you drew a line from the eye straight downward. A bucks' mouth 'hinge' in behind the eye.
Once you know what the difference is, you start to notice how how some hens are 'prettier' than others, and how some bucks are more studly than others.

Fish everywhere, every hole and seam up and down a stream, especially if you don't know the river well. Once you catch, remember that spot. If nothing changes drastically, fish will continue to hold in that spot for years to come.

I've found that sometimes I've caught fish that didn't fight worth beans and were hooked in the roof of the mouth. I've concluded that the hook is near, or in, the brain area and thus hinders survival based instincts. It doesn't always happen, but if you take close note of the location of the hook in the mouth roof, you'll see that most fish hooked in the same place will lack a good fight.

I don't fish spoons anymore for steelhead so I won't go there.

Good fishin'
