You know, Tracy, I wonder if it's possible to get larger trout that only the biggest LMB can eat.
Like, say, start with 1/2 to 3/4 pound trout. Too big for the smaller LMB, but great for the bigguns. That would still be true as the trout grow, at least until they hit maybe 2 lbs in spring.
Something similar with TP, too. Match the hatch, so to speak!
