Sorry, I wasn't advocating for stocking over viable wild trout populations. I was just saying that if it is going to be done in some cases, I'd like to see them at least not stock that species and really just rainbows only here in PA.I agree with most of what you said, though I'm not a big fan of stocking any trout into streams that have good wild trout populations. The trout that are stocked are often larger than their wild counterparts and can claim the better spots. Rainbows are the least likely to successfully spawn of the stocked species in PA. The rainbows that are stocked by the PAF&BC spawn in the fall and rainbow trout eggs can't survive water temperatures less than 40 degrees. The great majority of PA streams, especially the freestoners, get colder than that in the winter.
The only other disagreement is that I think brown trout after they reach 9 inches are more likely to eat fish, but will still eat lots of insects, crustaceans, or whatever they can catch.
Yes Browns do still eat other food, just that they prey heavily on other fish beginning at that size. It's part of what helps them grow larger and out-compete other trout.
