Ever think about a small vent cap like @angelapalmer said?

That's a great point about the fat cap, and it reminds me of how often we stick with a habit just because it's how we've always done it. You see it everywhere, from how people pack a dishwasher to the way they tie their shoes. Sometimes it takes a fresh pair of eyes to show you what you're really working with. For retail, a tight trim is just honest, because you're right, people are paying for the meat. A quarter inch is plenty to keep it juicy without feeling like you got cheated.

Avoid the creosote, seriously.
