Bacon can make almost any burger better.  But there are so many variables that go into the addition of Bacon.

So what do you prefer?

Thickness:  Very Thin ---------------------Very Thick (Chili's Big Mouth)
Quantity:  1---2---3---4
Formation:  Parallel Strips-----Cross-----Square-----Unorganized Mess

Thin, 2, parallel.

Thin,3,cross

medium thickness, 4 pieces, crossed over like this:  #

I really love the thin, crispy bacon and I like it in the formation of the number sign... "#"

:)

Have to agree with Jandurin on the # symbol bacon layout. It ensures a consistent bacon amount in pretty much every bite. Though, in my old age now I have switched to turkey bacon more often than not. It's not the same (not nearly the crispyness) but it still tastes pretty good.

Yeah, I like the number sign layout, thin and crispy.

Thick
3
Parallel

medium, 4, # layout

I'm going to agree with the # formation for the sole reason that merely parallel bacon runs the risk of a strip of bacon being pulled out with a bite too easily and thus being lost to the rest of the burger, dooming the diner to a few baconless bites. That's a fate I'd wish on no man. As far as thickness goes, I'd say not too thin, not too thick, I like it to be a bit substantial though.
