MOTM

Hi everybody,

Things are quiet now that Paul's on vacation, but I'm sure one of y'all
knows the answer to this.  With my first set of MOTM rack rails came an
instruction sheet which indicated that the rails had a preferred
orientation (back-bent flange on top or bottom).  Since then I've lost the
sheet, unmounted and mounted everything several times, and now I can't
remember which way!  So, which way should they go, and is there an obvious
reason to prefer one over the other?

peace,
Chris Jeris
