I' ve taken game with aluminum, carbon, ACC' s and all the animal I' ve shot with them are just as dead. I' ve had aluminum pass thru or not, carbons pass thru, or not and ACC' s pass thru, or not. There is advantages to each that I really like and disadvantages to each as well, the list is equal, so I don' t have a preference to any of the three. One isn' t better than the next, just different. Currently I' m shooting ACC' s as I have the last two years. Will I go back to aluminum or carbons again, yup probably will shoot both in years to come. I love to tinker, love to change and each arrow is just as deadly as the next. It' s all up to the shooter to perfect his ability, match and tune his/her equipment, stay calm and make the shot.
