You are correct Sir,
The humped fences, or dowels are just for poorly set up band saws. I have a 14" grizzly that wont drift at all. I use timberwolf blades, and when tensioned properly it resaws like a champ. I use a piece of melamine shelving for a fence and clamp it down with some of the rockler clamps for clamping aux. fences. I really don't think you need a humped fence unless you are resawing logs all of the time. It really gets old drawing the line on your wood just to resaw it. The few times I have resawed a irregular shapped piece of wood I just draw my line and free hand it no fence. Then it is on to the jointer.
