    Chain line precision

    I'm building up my new frame, and this is my first time building from scratch. I'm using a Phil BB the cups of which allow for quite a bit of freedom with the positioning of the cartridge in the shell. My question is about chainline: how precise should it be, and how do I check? I've got it set up; it looks straight, feels smooth; it is a bit noisy --but perhaps that's due to the new parts?
    Need more details? I'm using a 1/8" drivetrain: Surly fixed/fixed hub, EAI cog, Izumi chain, TA track crank.

    The better the chainline the quieter the bike in my experience.
    "We are few now, but one day we will rule." That's what one of my fixies whispered as I walked by. I nodded in agreement, and thanked it for not waking the others.
