Keel type bead head nymph
It's so fishy that a bait fishing expert (my former boss at work) who is a year older than me begged, "Can you give me some of it?" If you use tungsten beads and grab hooks, the center of gravity will be biased towards the eye side and it will stand up. This makes it hard to get caught even if you roll the bottom. Please arrange the body material as you like using the materials you have on hand.
When the water is released immediately after the fishing season is released, fish are often found at the bottom of the pool. I'm reluctant to cast a nymph alongside a bait fisherman, but if you really want to see fish, try using it. I think it's almost certain that you will catch a fish. It has been endorsed by the aforementioned bait fishing expert, who has praised it, saying, "This is amazing. You can catch more fish than bait."
