The Morrish Hopper works best along grassy banks, undercut edges, meadow streams, riffle margins, foam lines, and slow seams near shore. Cast it close to the bank with a natural little plop, then let it drift like a real hopper that just made a poor life choice. Trout often use shade, bankside cover, and broken current for safety, so those edges are prime places to show them a big terrestrial meal.
