Stretched Out Line

[jakester]

I HAVE A BEST BAR & LINES ONLY 4 MONTHS OLD WHEN I BEGAN KITING.
I WAS RIDING TODAY AND MY KITE BEGAN TO DIVE TO THE RIGHT SHARPLY ON ITS OWN. I LOOKED AT THE OUTSIDE LINES AND NOTICED MUCH MORE SLACK IN THE LEFT OUTSIDE LINE. I LANDED THE KITE AND CHECKED THE LINES AND FOUND A 6" DIFFERENCE!! MY ATTEMPT TO FIX IT ON THE FLY WAS TO TIE A LOOP KNOT IN THE STRETCHED LINE, HOWEVER, THIS JUST MESSED UP THE AERODYMICS OF THE KITE.
1) SUGGESTIONS FOR TEMPORARY FIX?
2) I'VE HEARD SOME GUYS ON HERE MENTION Q LINE. ANY INPUT FOR AN UPGRADE AND WHERE CAN I GET SOME?
THIS WAS A HASSLE AND I'D RATHER NOT DEAL WITH IT AGAIN IF POSSIBLE.
I ALSO CHECKED THE OUTSIDE BRIDLES AND THEY APPEAR EVEN.
THANKS FOR ANY VETERAN INPUT...
