I have two lures that I usually fall back on for trout and medium to large bluegill.
1) 1/32nd silver / yellow bodied panther martin inline spinner (usually when they are more active)
and
2) Gulp 1 inch (2cm) minnows rigged onto a 1/64th or 1/32nd jig head. I toss them out, allow to sink for about 3 seconds, then slightly twitch the rod up and down and reel in very slowly. This has been very effective for me. More so than any other soft plastic I have ever used in heavily pressured ponds.
I mainly use it for bluegill & trout (mainly rainbows and finicky browns), and every once in awhile will catch a smaller model 1 lb LMB.
