There are pluses and minuses to each. I've become an ardent user of carbons for one simple reason. I'm able to take very light, stiff arrows and put a huge percentage of weight on the tip to make extreme FOC arrows, that hit with unreal penetration and have great stability in wind and other obsticles. They're not perfectly straight all the time, and the spine issues are real, but I find that at typical hunting distances, those downfalls do not really get in the way. On the other hand, the advantages of a heavy, high FOC arrow are too great, in my opinion, to give up.

I spine tune my carbon arrows and cut from both ends when trimming. After cullling the worst few from a dozen, I usually get the rest to hit right where I'm aiming out to distances well past my hunting range.

Like Dr. Ashby says, the advantages to heavy weight and extreme FOC arrows are there, on every bow, every animal, no matter how small the animal or how high the draw weight. It's not just low draw weight, traditional shooters who see tremendous advantages from such a setup. It's everyone.
