Jack I have friends that feel the same as you.
Its not the pretty but the difference in speed I dig.
Its as if I know what kings are about to do while steel has me 2 moves behind just trying to catch up.
Ialso love coho.
They fight about the same as steel except when I punch a steelhead they go crazy but a coho I have to show some muscle before they go ballistic.
After that it is game on with either till they burn themselves up and become managable.
I like the chrome before the water drops below upper 40s.
Once it chills down they lose 20% of their wildness in my mind and while still awesome fighters they are not the same as the earlier fish.
dw I used to fish lots of popcicle type flies and they work great.
I find that a little smaller flies with less flash and movement caught more kings for me.
Things that look more like what they are programmed to chase in the lake.
A preditor is always a preditor even when they aren't feeding is my therory.
