About 15 yrs ago I was getting taken to the woodshed pretty badly. After falling down a set and a break I cracked my frame...because....the racquet... slipped out of my hand (yeah, that's the ticket). Anyway, the tension went from about 60 lbs to virtually nothing in an instant. I decided to go through the motions and finish the match, and lo and behold, a new player was born. In that same instant, I went from a 4.5 to a 5.5, and yes, I won the match. Since then I string at 12 lbs. Yes, that's right - 12 lbs! Of course they say string tight for control, loose for power, but at 12 lbs there is no power, you have to generate it yourself. On the other hand, there is incredible control and spin. The ball stays on the strings a fraction of a second longer, allowing for impeccable placement, topspin, slice and underspin, as well as feel that higher tensions cannot come close to. I sent an email to usta prez Patrick Mac to pass along my discovery, however he probably thought I was crazy and didn't reply. But you know, they told Christopher Columbus he was crazy when he said the world was round, they told the Wright brothers they were crazy when they had a dream to fly, and they told Isaac Newton he was crazy when he boldly proclaimed he could bake a cookie filled with a fig. Brothers of the courts unite! Awaken the tennis player within, become one with the ball - string at extreme low tensions!
