I spent the last 3 summers in Montana working in a fly shop and fishing. Frankly I ahve caught enough trout in the 16-24 inch range recently to last me a decade or so. There is no force on Earth that would convinse me to take a trout trip to Montana During a perios of good Northwest Steelheading.
In my opinion there is no comparison between a big trout and a small steelhead.
