Big Rainbows-freshwater. Have a San Juan River trip next week and plan on finding some. Being landlocked, I don't have much opportunity to fish the salt, but expect that to change in the near future.
They're all fun to catch. I like the small native brookies (we call them "speckled trout" in N. GA) but I have to say, there is something to be said about the fighting power of a big rainbow.
