Hey Greg/MO!! I apologize for posting a question that completely consumed your time. However, your response was more than I could have hoped for. It was clear, concise, and to the point. I really appreciated your pictures. They probably were the coup-de-grace. I have already ordered a 600 PC for my new Guardian and can't wait to get it on the bow. Thanks again for the great information and good luck on your upcoming Elk Hunt. And thanks to all of the other respondents to my posting. They were all very helpful.
