Recently, I changed my racket to Wilson Juice 100 and strung VS gut at 60 pounds. It snapped in a month. I play usually twice a week. Each session is 2 hour or 3 hours. I like to hit top-spin. When I used multi on Pure Drive, it used to last more than six weeks. I thought natural gut is more durable than multi. So, I never expected it to snap in a month. Is this because of racket? I can't afford a set of natural gut every month. If Juice 100 is a string breaker, I might have to think about gut hybrid or multi full-bed setup.
