It’s been years but casting spoons at obvious structure like points, bluffs, slides, etc yielded bulls in the 1-3 lb class is pretty consistent. Just like targeting bulls in rivers, find rocky/boulders shoreline and bottom and good chance there’ll be bull trout around.
Be prepared for lots of grizzlies and, with the pathetic state of Interior salmon runs (both Chinook and sockeye) they’ll likely be hungry!
