I can't comment on the Life Ender, but own a Kanati and it is a fine shooter, stable and shoots to the spot, very quiet bow and doesn't take a back seat in speed next to my Centaurs. Is a breeze to tune, mine will shoot everything I have run through it. I have, and have owned bows that cost twice as much that won't outperform the Kanati. Get one in your hands, you will be very pleased I would bet. With that said, personal preference is what it is !! Good luck with your search. I call the Kanati a Shrew on steroids.
