RE: New Arrows
The LiteSpeeds will definitely pass through a whitetail but they aren't going to survive the impact with the ground on the other side. They're pretty thin walled. If I were going to buy myself a new 3D shaft today I'd be looking hard at the CX LineJammer or Easton Fatboy but I don't take speed into as much consideration as most, which is why I said the LiteSpeed in answer to your wanting a faster arrow. If you want one shaft to do it all go to the A/C/C.
