That's what I was taught too, when the reins are being used and leverage
is the issue.  Could it be though, that when the bit is just hanging on
loose
reins, the curve affects the center of gravity of the shanks, and
therefore
the angle at which it hangs, which might only matter if the bit has a
port
to encourage the horse to hold his head in alignment with the plane
through
the port.  With a straight ("mullen") I would agree there could not
possibly
be any effect.

Personally, I also am very skeptical of any and all "bit" design
issues.  Even
as a relative novice, I think I have seen enough to believe that
whatever 
effect bit or hackamore design might have is generally much less
important
than the rider's hands and seat.
