A Tomahawk? Mhhh...
Regarding the silent Parker bow. The problem is, it is only silent if you hit both lungs, the heart, the brain or the neck bones/spine. Due to the lack of power you won't hit both lungs on most game and the heart is kinda misplaced for some animals and I still struggle to be 100% sure where it is depending on the species, which freaks me off. The roe deers heart for example is, according to the hunter mate, completely misplaced. I wanted to do some tests and aim for the exact position where it is in RL, but I havn't done it yet. Even with virtual animals "testing" feels kinda wrong to me.
Anyways, if you hit it and the animal runs - they all run. A problem currently being discussed in the official forums.
It is a great bow non the less and still on my "maybe" list. Right now its just no priority for me.
