Sorry, I have no clue as to who Theo is, but he ties a mean looking hopper. I really like the Loco-foam on the pattern, but it actually reminds me more of a cricket than a hopper (same thing, or close enough) at least in my local anyhow. With all the dry weather we have had in my neck of the woods, I’m expecting quite a few of the hoppy little critters to end up on a float downstream. I’ll be trying out this along with a few other hoppers (expect to see more posted) for the fall season. Enjoy, and be sure you are stocked up on crazy glue.
