I haven't been fishing lately, but back in the spring & early summer I mixed a lot more smallmouth fishing in with muskie fishing. Instead of jetting through unproductive holes, I would drift through and fish for smallies. My hours/catch for muskies fell substantially from previous years. I think it's because I wasn't fatigued as much when it mattered... Or maybe it was just coincidence who knows.
I guess you don't have that luxury with clients that want a picture with a big toothy critter!
