If your finished arrow weight is 400 grains or better, and you can get the Landshark razor sharp (assuming it's the 2 blade with no bleeders), be selective with your shots, make sure you have perfect arrow flight (a wobbly arrow will rob you of penetration), and of course be able to put the arrow in the spot, your set-up should be fine for whitetail and smaller game.

I agree completely.
Who cares if you kill a deer with carbon, aluminum, wood, or heck, even a rock, as long as you make a quick, clean kill.
