I use the Blackhawk Vaper "all Carbon 4000". I really love these shafts. They are straighter than what they advertise, and the weight tolerance is unbeleavable for the price. I think on my dozen arrows there was only a difference of about 3 grains from the heaviest to the lightest.

They tend to pull a little harder out of the 3D targets but they hold up well. I use mine primarily for hunting, and with they have some nice weight for hunting if you like a heavier arrow.

Highly, Highly recomend!!!!
