Size does matter, yet overdoing it is also not recommended. It's common knowledge that a bratwurst of commendable size requires large amounts of blood, and the average male has only 3 liters. Not only that, having a huge wurst is not very handy or pleasureful when it doesn't fit in any tasty, moist buns. That said, having a medium-sized wurst is optimal. You can carry on enjoying your oversized, soft wursts and hot dogs while my girl and I have fun with a tasty, firm and hard wurst of mine. No contest, I tell ya.
