Interesting responses, a little surprising to me. Love them all, but in my experience the wild (almost always non-native) rainbows have fought the hardest, which makes for a little more fun.
I've never had a cutthroat or a brown make more than one serious jump while hooked, and I've found it pretty rare to see a cutt jump even once. I'm just happy to find any trout rising to dries, that always makes for a great day, even if they prove difficult/impossible to catch.
