Someone tried to sell me an old Tembo a while back that had a four pin sight on it, the side bracket kind. I was pretty certain those filled holes would drive me crazy, after i threw the sight away. Some things are anathema. While I don't care how anyone shoots their Hills, except one with a sight on it just brings a sarcastic devil out of me. An expert, with three whole years of compound experience, he never even tried to shoot it without the sights, nor could he get it back.
