I think Esshup covered it pretty good, and will just add my simple experience for my situation.
I stocked 50 RBT in my 1 acre pond to knock back a GSF hatch before my actual stockers went in. The GSF were about 1.5-2" and the trout were 11-13" when stocked. I did NOT feed them from stocking thru winter. They did hammer a lot of those small fish. Now I don't have actual proof of that, those GSF may just have been hiding somewhere that I no longer could see them, but the trout grew very well. I then fed them some into late spring and early summer. When I harvested them, I never found any fish the stomachs of the trout, just feed. That kind of goes along with what is often said here on the forum. They much prefer the feed.
Now a question/thought that may pertain to you and perhaps someone could answer. The LMB are more fusiform(?) than BG, so would the trout go after them first???? That may help you out in having to thin so many next year, but if they go after the forage of the LMB, perhaps it's not good.
