I would not sweat the differences so much. Most people are shocked when they learn that there can be as much as five or more grain differences from one dozen to dozen with carbon arrows of all types.
If turly a matched set are what you are looking for, you might have to got through the same process of spine testing, and weighing that wood shooters go through.
I have used AD and loved them, they got hard to find and I was pretty upset, until I found the Grizzly Stiks, which IMO are tougher and gives heaiver arrow weight.
For me, full tapered shafts, wood, or carbon provide the most efficient use of a bows energy, allows the shooter to get good flight from a wide range of draw weights.
I just wish someone would produce a full tapered aluminum shaft, that would be my arrow of choice. I guess I had better get started on it....
