Hi! I've have just restrung my badminton racket and at tension 28lbs 2 days ago with nanogy 98; and i have always strung it at that tension, and only with this recent restringing that i noticed the head of my racket is slightly warped can it still be saved if i cut the string? I will post the pic in a few hours when i home. Pls help me with advice thank you!
I'm not saying that the lower tie off will cause the racket to warp. I've tried it a few times and see it once or twice especially having a extra cross at the top. For myself, I will not try any fancy tie off holes.
My guess would be due to the fancy tie off at the top. If were to follow the mostly recommanded tie off at a5, I think this warp could have been prevented.
Tie-off away from the center mains has its reason IMO. There was once I was pulling too hard with a starting clamp during tying off and the main where the knot was snapped. I think it was a ZMm62 string. Tying will make the main become thinner at the knot, and thus become prone to snap at the knot IMO. So, I always tie off at the 10th main, away from the center mains. I hope it makes some sense.
