If you sound like a duck, a call is a powerful tool. Can you kill birds without one, sure can. I use a call whenever possible I think it helps. I also know when and how to use it. It's hard to tell through the Internet how good you are on a call. I believe every call on the market will kill birds. I also think that higher end acrylic calls can give you more range, IF you have the skill, or the time to practice.
