your speed and k.e. is far greater than any animal on this planet can handle at any accurate shooting yardage!!! how do you think the indians killed moose ,elk,bear? not with a bowtech or a mathews!!!! only with sharp arrow heads,shot placement and skill to get inside a comfortable kill zone..get back to the KISS method and you'll be more successful in your hunts. technology is an advantage, not a mandatory factor. if you shoot a 350 grain arrow in the kill zone at 30 yards and a 550 grain arrow in the same spot at the same yards, both will get a clean pass through. only at longer ranges does heavy arrows with greater speed + more k.e. = any more advantage..i've got 2 velocity specialists in my family..don't get caught up in the marketing hype. shoot accurate at your comfortable range and hunt within that distance. isn't that what bowhunting is all about, getting close to you prey???
