Cook the pasta according to the package directions; drain, rinse with cold water to cool the pasta, and drain again. Set aside for 5 minutes. [Best to cook 1 minute less for al dente.]
For the dressing: Stir together mayonnaise, sour cream (or Greek yogurt), pickle juice, black pepper, onion powder, cayenne pepper, and salt in a small bowl until smooth, set aside.
For the salad: In a large bowl, add the cooled pasta, pickles (sweet and dill), cheese cubes, bacon, and 2 Tbsp fresh chopped dill; add the dressing, and stir to coat. Salt and pepper to taste!
Refrigerate at least 1 hour and up to a day ahead.
Before serving, garnish with more diced pickles and remaining 2 Tbsp fresh dill on top. Serve!
TIP for post: Substitute grated cheddar cheese (wide pieces, not finely shredded), and save time on dicing!
