Any large, say 4lbs or bigger, SMBs I have hooked were among the most harrowing angling encounters I experienced. I think the biggest one was in the 6 to 8lb range. That was back in Ontario. That fish immediately jumped repeatedly then sulked for a while then jumped again a number of times before diving and pulling my leader leader through a large mass of large rocks. I think it knew what it was doing. Another fish that was not quite as large also exploded from the water repeatedly. likewise I had it for a while before it dived before drew my line across a pair of waterlogged moorage floats that hung below the water like mines leaving me with another broken leader.
I caught my first SMBs in Quennell Lake on the Island in 1973 when I was vacationing with my parents. My father and i caught a large number of fish mostly, in the 1 to 2lb range. They really impressed me with how hard they pulled.
I have caught some duds too!
Overall for a given length SMBs will weigh more that trout so they will pull harder. They jump freely but not as high as trout. Trout are much faster. Any salmonid is capable of running farther and faster than any bass. i think SMBs are smarter than trout, at least than rainbows and cutthroat.
I don't know what sort of trout this guy from Colorado was catching. He mostly talked about cutt-bows. How vigorously a fish will fight when hook varies with the stock, river, species and water conditions. When temps are ideal for SMBs they are tending to marginal for most trout. When i fished the Madison I really found the rainbows rather tepid. the browns in that river fought far better and generally grew larger.
Too many variables for me to attempt a call but I do enjoy the research!
