In addition to Cecil's concern, I was also thinking about predators and prey! Those 9 pound largemouth bass would dearly love to eat a 8 to 12 inch tiger trout, I suspect. The trout are fusiform (torpedo shaped) and soft rayed (no spines to get in the way).
I don't know if it still true, but the Colorado state record largemouth bass came from an impoundment out near the Wray hatchery. They stocked the impoundment with catchable size rainbow trout (e.g., 8-10 inches), and those big bass fed very well on those naive trout from the hatchery.
So, I guess that I'd suggest you consider what size of tiger trout you would stock. What would it take for them to be big enough to avoid being eaten??
I don't have any direct experience with this situation, but I think this is good food for thought.
