Cook the pasta until al dente according to package directions. Drain and add 1 cup of pickle juice to keep it from sticking together and for flavor. Let it rest for 5 minutes and drain.
Whisk together the mayo, Greek yogurt, hot sauce, pickle juice, salt, and pepper until smooth.
Place the pasta, sliced pickles, diced cheddar, chopped onion, and fresh dill in a bowl. Drizzle the dressing on top and toss. Refrigerate for at least 30 mins before serving.
