There are many many different spine groups in both wood and aluminum in order to find the shaft that works best for you.
In Carbon, there are on average only 4 different groups.
With these 4 groups, we are capable of making them fly for most every draw weight, length and bow type.
If you can't find carbons that work, it is because your not willing to learn what it takes. I'm sure when aluminum arrows first came out, there was a lot of wood shooters having problems swithching too.
Covey, why compare the cheap aluminum with the "high end" carbons. There are many carbons available for nearly the same or less than aluminum.
I also don't see the big problem with front weighting. We now have many different options to get the extra weight up front to make it easier and it has been proven to improve flight characteristics and penetration.
