Nothing wrong with AD shafts. I have found it impossible to determine the spine of various AD shafts from the manufacturer's description though. That's why I use Easton Axis. Skinny shafts and very tough, IMO. The black ones are about 15 grains lighter than the wood grain shafts, so can achieve just a tad more FOC with the same amount of weight up front.
There are lighter shafts around, but I'm not certain they're as tough. Of course, a lot of folks "foot" their carbon shafts with an inch or so long collar made out of an aluminum shaft placed immediately behind the point. Makes them less susceptible to mushrooming, and adds FOC.
