I bought a new bow because the 05 Switchback I had was too short of a draw length for me. Yes, I killed deer with it but my form was suffering and I was somewhat inconsistent. I sold that bow and got a brand new 07 Commander for less than what I sold the Switchback for!
Do I think it will make me a better hunter? NO
Did I get it because I wanted a "pimped out" bow? NO
I got it because I needed it.
