Last night I re-strung my vantage frame with legend 18g. I noticed upon opening the package that the color was yellowish and not the clear smooth string I have used and strung before. The most recent set felt not as smooth as previous sets and also was very resilient and kept coliing and kinking after a light pre- stretch. It was also a pain to string compared to other 18g legend sets,I have strung. I played with it tonight and the string felt like it did not hold tension, strings kept moving. Could this be a faulty set? Previous sets strung up real easy and held tension well and the strings hardly moved.
