bcvd, I would highly recommend a high quality set of strings and cables for your bow. IMO, the strings are the single most important part of your bow. They hold it all together!

I personally like 8125 material for all of my strings. My current bow, a 2007 Bowtech Allegiance still has the factory set on it. However, Bowtech uses very high quality strings on their bows and my peep, along with timing has not budged since approx 50 shots after buying the bow.

You'll pay a little more for good strings and cables...anywhere from 50-100 dollars, but they are very well worth the extra money.
