In terms of durability? So I usually string my racket with BG66 @ 26 lbs. I plan to switch to BG65 TI @ 29 lbs. Will there be any difference in durability?
The main difference you will notice is that the Bg65 ti will be less repulsive than the bg 66, the sound of both the strings will be different. Bg65ti is a good all round string and will of course be more durable than the bg66, for example if your bg66 breaks in 3 weeks, bg65ti will stay up for at least 1 and half month. Also you might take some time to get used to the 65ti as the repulsion will be kind of less compared to bg66 Otherwise, if you are looking for a durable string with good repulsion, try out nbg99 or nbg95, also try the bg80. Not much to change, but it will take some time for you to get used to How often do you play? singles/doubles? which racket and specs(3u or 4u). Also like this reply if it helped you
