I respect Outlaw, he makes a nice bow, but I find his advice to make it as if the pins weren't there to add more risk into the equation.
Admittedly I have seen many bows where this has been done and the bowyer manages to get away with having an uncompensated flaw.
When a bowyer is learning, or making a narrow bow, or one with a heavy draw weight, or performs near the staves limits for its design, these small flaws that have been left unattended are usually where you start to get problems, or even an outright break. This can easily be avoided by leaving a little extra wood in the width of the limb to compensate for the pins.
