This thread itself validates the need for an aiming sub forum. In one day just the idea of it has generated 6 pages! With a healthy dose of bickering along the way.
On the contrary I was directed to a site that contained an explanation and example of Offset and Pivot Aiming Systems. That in itself is far more than I read here. And I'm not spending 50 or 80 bucks on a DVD to simply find out what the hell their arguing about.
