Tough decision. I probably would have wasted it, but thats me...based on my experience and where, when, and how often I hunt. In my humble opinion it's not what other hunters think..it's what you think. There is a case for both sides of the argument - but in the end, the decision to squeeze the trigger rests solely with the person with the gun to his shoulder.
Are you comfortable with your decision?
In the end thats the only opinion that counts. It sounds like you are. I hope you are blessed with a 175+ next year!
