I've had a couple of Yonex Ti-8 rackets strung at 28lbs with BG-65Ti. My question is, how quickly will these strings lose tension and how low will they go? I've been told to expect to lose about 2 lbs in the first month, then another 2 lbs in the next 2 months or until they break. I've had an older racket strung with BG-65Ti before, at 21lbs and they didn't seem to lose too much tension and lasted a long time, more than six months. I've just never strung to a high tension before so if anyone who regularly uses these kinds of tensions can help, then please advise.
