Ummnnn, I still think you need to bump up the wheat. Maybe do 6-7 pounds of wheat and 4-5 pounds of pilsner. Also, for your first Hefe, you might want to go with WL300. I feel like that's the gold standard for wheat beers. Lots of banana, bubble gum and clove. The WL380 (Hefe IV) is a clove bomb, with subdued fruitiness. It's good, but probably not what you've got in mind. Just my 2 cents though...
