My buddy has a terrible habit of leaving his tennis bag in his car and that's something I never do. I lent him a cheap stick some time ago and he keeps asking to borrow it in case he needs an extra for someone else. Well, he mixed up the cheap HEAD titanium with my HEAD LM Prestige and that's where I got screwed. It had been a month since we last played and he left the Prestige which was strung with nat gut in his car the whole time. He took it out of his tennis bag for the first time and 2 mains were snapped. This is inexcusable ignorance. I'm not even lending this clown the titanium anymore.
