With the manufacturing techniques and production tolerances what they are today, I do not think "break in" is as important as it used to be.
With that said, I personally would use the engine over its entire rpm range regularly during the initial 500 miles, dump the oil, then business as usual.
My car says to use 5W-20 oil, this tells me that machining is pretty tight and that thicker oil formerly used to make up be higher tolerances is no longer needed.
Then again, I don't buy new. I let someone else take the initial depreciation. I buy 2 - 3 year olds with some manufacturers warranty left.
