Hi guys! just wondering which string can hold its tension the longest? i jus strung my racket at 26lbs using a BG65 string and i wan it to remain at 26lbs for a long time. But now i jus read some posts n replies, it seems tat BG65 loses its tension veri fast..but i look at the properties of the string, the durability for BG65 is excellent and i thought tat the durability means how long the string is able to hold its tension. So since BG65 cun hold its tension, anyone noes wad string can hold its tension for a long time??
