What type of strings are you shooting? Some factory strings take a while to settle in. Most after market strings are very solid and do not twist. If you do not have the tool for tightening your D lood you can take a screwdriver(preferabbly a phillips) put it thru the D loop , hold the riser and PULL!!!. Draw your bow to see which way it goes. Turn you D loop slightly to allow for the rotation. Depending on the string type or manufacturer it may not stop moving. If it settles down now it may move again in the heat. I shoot winners choice, I made my own strings for years, It was less time consuming to order strings from Mike and just put them on the bow. If you have time and the knowledge making strings can be a good thing to know. I place my new string on the bow,line up my D loop with the peep and never touch it again.
