Does anyone have any hunting experience with these arrows? I've read that they are significantly lighter and stronger and will penetrate better. This latter point seems counter intuitive. I'm presently shooting 27" gold tips with 100 gran heads at 278 fps. If I were to make a change, I'd still want to be able to shoot 100g heads. Are the benefits worth the price in a hunting set up? What are the downsides other than costs? I'm presently shooting snyper mechanicals so I don't anticipate any planing problems. Please advise.
