Swamp Dog is correct. There are quite a few carbon shafts to choose from, and weighing as little as 5.5gr/inch up to over 12gr/inch. You still have to deal with being properly spined, however, so this narrows the choices somewhat. I say to plug into websites of arrow makers and see what they offer. The array we have to choose from is quite astounding, along with the quality and price ranges. That being said, I think you'll find that lighter usually mean better quality (target & 3D arrows) and priced accordingly.
