I always shoot what I hunt with. 68 inch longbow, 55lbs @ 30 inch draw, with 584 grain arrows. I am a hunter first and foremost and I use 3D shoots to improve my skills so I can make a clean kill. That is what all of my shooting is about, a clean kill taken at short range.
Do I like to win, you bet I do. Do I care if some guy I am shooting against is using a high end target bow and beats me. Not a bit. His equipment is his choice to make and he is welcome to it. I cannot push my ethics, equipment preferences, or views onto anyone else. If you feel outraged or offended that someone else shoots something else, you can of course just not attend that shoot again. In my mind that is self defeating. We need to support all archers and clubs to keep our sport healthy and enough members shooting and hunting to keep the Anti's at bay. I embrace our fellow archers, enjoy chatting and learning about each one of them and their equipment, and of course love it when I shoot better on a target, a course, or a full shoot. It happens enough for me to look forward to it.
I know that I am competing against my best prior score and nothing else. I cannot expect and don't expect to beat someone who is better than I am, or has better equipment. I also don't complain when I think the clubs set up is unfair. Life is tough and the world is unfair. As Grandpa used to tell me "Get the he@@ over it boy. Life isn't fair and if you think it should be, your going to have a rough life."
