You did well by even asking your question on a big forum like this. Asking a question is never stupid and would help a lot of people get a better hunt in the end. I went with goals and sizes in my mind also and still do and I am going back for my 5th time. Just don't get caught up on the size once your happy with an animal you see and want to hunt. 1/2 or 1" does not mean much if you take old mature animals and have fun doing it.
