For an arrow that is as light as they are, they are pretty tough. I damaged a couple of them in my basement. I have a Deadstop Quad target with a concrete wall behind it. Sometimes, I don't rotate it often enough, and have mushroomed too many ACCs that way (gets expensive). The Cheetahs have survived some pass troughs when I've heard the dreaded sound of the field pt. hitting the wall, but the two I damaged were shot with the Oregon Black Knight set on #70. Never should have shot into that target without additional backing. Still, the worst of those is cracked about 1" into the shaft. I am shooting the Cheetah Hunters (.006), but they all spin almost as nice as the ACCs and shoot just as well for me. The 3Ds should be just that much better.
