RE: changing my righthanded bow to a lefthanded bow
I'm a lefty and right eye dominant. My parents figured that out a long time ago and bought me a right handed bow. If you are left eye dominant you have 2 choices. Buy a left handed bow or learn to shoot with your left eye closed.
You're better off buying the left handed bow in the long run though. You'll shoot it more consistently and won't be fighting what's natural. Also, you are better off learning to shoot with both eyes open.
