I know the Doc bb is 68mm. But, what length do you run to ensure optimal chain line. 113mm or 118mm ? And I will be slapping on a chain guide, if it helps on determining my bb length.

I am guessing that you are talking ISIS and not another spindle type. It depends whether you are running a cassette or singlespeed, and to some extent it can depend on your crank arms.
