It seems the conventional wisdom is that polys should be strung around of below 50 lbs. And that poly loses tension quickly. Ignorant of these facts over a year ago, I strung some Gamma Zo Tour 16 that my friend gave me at my normal tension (which was 59 lbs. on a Yonex RDIS300--this is one pound shy of the max. range. It lasted me longer than the string I was using at the time (Prince Lightning XX) with it being playable throughout. I've also recently played with and liked Topspin Cyber Flash 16 @ 60 lbs (mid-tension on my RQIS 1 Tour XL.) What struck me with this string was how well it seems to hold its tension. It was a little stiff, which I don't mind since I have two-handed strokes on both sides, but the tension feels about the same as when I strung it over a month ago (I play about 8 hours a week.) I mean, I thought polys were supposed to be terrible at maintaining tension. So my question is: Is my experience unique? This string job with the Cyber Flash strings has already lasted me twice as long as my previous string job: 850 Pro multi, which began to catapult the ball at a certain point. And the tension feels about the same as when I strung it over a month ago (I play about 8 hours a week.) Also, are there any specific polys that hold tension well and remain playable at around 60 lbs.?
