Your project with the Rainbows sounds great, ML.
Just to jab at you, however, the trout approach is "tried and true" for big LMB, as you know, for the southern CA lakes. I have a magazine with an in depth description of those lakes which I'll have to recheck, but most of the lakes are small (less than 50 acres).
What will also be interesting is to see if your LMB "instinctively" know that the trout are a nice, fatty, high protein meal.
