I don't buy that wood has to be an inferior shaft material. If I didn't believe they could be very consistent and dependable, I wouldn't shoot them.
It's all about what goes into making them, and much more does go into making a good wood arrow than does a good carbon or aluminum, but that's part of the mystique. If you get good shafts to begin with, sort them closely in weight and especially spine, straighten them well, put a waterproof finish on them, tune them well, and put the closest matched arrows in the front of your quiver, I'm convinced you will have a dependable arrow that will shoot just as well as carbon or aluminum. One disadvantage would be durability, but I find when I put internal footings in my arrows I rarely have any break...in fact they're more durable than many carbons I've shot, though not all.
Interestingly enough, at least half of the carbon shafts I have put on my spine tester have come out less consistent than a good set of wood shafts...if you're going to shoot carbon make sure you're getting good quality, matched carbon.
Another thing a lot of people don't think about is taking small measures to bring your shafts closer in dynamic spine. Weigh all your points, nocks, and feathers. Put the heavier points and lighter feathers/nocks on your heaviest spine arrows and vice versa. We're talking about maybe 8 grains total here, but that equates to almost 2# in dynamic spine, which can't hurt.
