Well, that goes without saying. A hefe, you obviously want the yeast character to dominate. For me, however, I don't brew that many, if any, yeast dominate beers. So US-05 is a great yeast to feature more of the hops/malt balances.
Dean, I get what you're saying. But what does JZ have to gain by telling you to pitch a certain amount of yeast? It's not like he's selling a product and wants you to give him money. He's trying to tell you that that is the amount of yeast you need to pitch to get a "proper" fermentation and make great beer versus good beer. But, that's just his opinion based on his experience (I guess...). You do what you like, it's your beer. I don't follow his pitch rates either, but I'm just playing devil's advocate here.
