thanks L4L and Irvin. seems like one of my outside main is a little bit loose. i just finish the string job because i was too tired to pull everything out on my crosses.
Also I cut 21' for my main and set my tension @ 46lbs because its a stiff poly. On my last pull on both side #9, i fell short pulling on my gripper. I re done it again twice with different technique. But it is still short. Will this string be garbage now?
