Please look to the following things: (See photos)
1. The difference of the loop (length) between a new string & the old string.
2. Is the old string looking good enough - looking to damage.
3. The difference in lenght between both loops on the old string.
Foto 1:
new string: 3.5 cm = 1,4 inch &
one side of the old string = 4,0 cm = 1,6 inch
(0.2 inch difference between the old & new string)
