Hi Fullcapwearer,
That area that you're referring to is know as the area directly below the occipital bone (lower part of the skull). Since the area is basically neck muscle and is used to rotate the head it's important to get a good secure bond as this movement causes stress on the bond. You're right about the length of the template. A shorter template will reduce the stress on the bond. But you don't want to go too short at the expense of looking unnatural. The other thing that I suggest to full cap wearers is to order the back and sides with poly to have a smooth surface for bonding. You need a strong bond and poly on the back and sides gives you a strong bonding area.
Regards,
John
