Lately I've started paying more attention to how I string. I've also gone up on tension from 40s to 60 and I've noticed that the hoop of the racquet is stretched out nearly a finger tip away from the 12'oclock mount. I don't know if this is normal and always occurred; because of the higher tension, I'm spending more time letting the string stretch that I noticed this? This has made me a bit anxious to move on to tensioning the 2nd main at the throat which seems to bring the racquet back to normal. I've wondered if it is recommended to pull tension on the left main#1, and feed the right main into the throat and then double pulling (right mains 1 and 2) there to correct the stretch quicker? I'm using an Alpha drop weight stringer w/ fixed clamps and 6pt. mounting system. Now that I think about it, I recently strung up a racquet w/ Poly mains at 35# and didn't see this. My racquet's a Yonnex w/ recommended tension 55-65#. I was using Laserfiber Laserlite XL. There are no cracks and to be honest, I don't notice anything when I play. Is this bad for the frame? Will a starting clamp alleviate this? Should I be measuring the width/height of the hoop pre and post stringing?
