I don't think guys that chuck huge streamers believe it's the only way to catch BIG fish. We see BIG fish caught on small flies all of the time. Big streamers select for a specific kind of fish. They select for aggressive fish. So, when you swing big streamers or strip big streamers, you don't catch often, but you do catch aggressive (and usually BIG). They select for rod shaking fun. I love the take of an huge brown on a stripped articulated streamer. I love the hit of an aggressive steelhead on a big streamer. The ride is incredible. I think the real issue is the elitist attitude of those hung up on that fishing method. We need to do a better job of agreeing that the thrill is in the hunt...no matter how we do it. And if other guys do it different, it's ok.
A lot of it depends on the stream, the time, and the conditions. Fact is, it's a total waste of my time to chuck big streamers in the middle of the day in the low and clear. Evening hatches probably do fish best at those times. You are absolutely NOT crazy. I applaud your ability to land the BIG boys on a small dry.
I watched a buddy land a BIG brown just shy of 20" last week on a dry fly and it was pretty sweet. At the same time, he thought it was pretty interesting how many fish I moved and caught on streamers.
I say we do a better job of learning from and supporting one another rather than feeling our chosen method is superior. I don't think my big streamers are superior, but they sure are a riot. That being said, I get board with my big streamers and their lack of production and revert back to dead drifting, high-stick nymphing, and dries all the time because they are more productive and I need to feel a tug on the end of my line more than I need to say I caught something of one of my monster streamers.
