Helping a friend of mine on his Hoyt charger bow. we are getting new string and cables for it. he does not know the model year of the bow. how do I find that out? Tried calling Hoyt customer service but they say they are out all week for the unveiling of 2016 bows. can I just go off the string and cable lengths on the bow to get the correct set of strings and cables or do I need the model year. I figure model year will make a difference on the servings on the strings and cables. this bow does use a plastic cable slide
