For a small profile request, these are the strongest matches because they all present a compact bait shape without looking oversized. Kisha's Sugar Momma - Umpqua is a compact streamer with a small profile and lots of movement. SquareGil 4" crankbait is a smaller hardbait with a tight wobble and a bluegill-style profile. Small Batch Slide Baits and 3in Shrimp Tail are both slim soft-bait options for a natural look. If you mean a small-profile offshore trolling bait, Bullet Head - Rigged Wahoo Trolling Lure - Small is the compact trolling choice here.
Switch to a larger or more specialized bait if fish are keying on bigger forage, if you need more water displacement, or if the bite is deep and you need a heavier presentation. If you want a true surface dry-fly small profile instead of a lure, the fly options here are Snow Shoe Yellow Sallie - Solitude and Harrop's CDC Biot Emerger BWO - Solitude - Mayfly Dry Fly.
