I just ordered a set of Technifibre Biphase X-one 16 gauge and Topspin Cyberflash 17 gauge strings from tennis warehouse to be put on my nsix-one 95 16x18 racquets. I have some problems with my elbow and, to a lesser extent, my shoulder when I play two or more days in a row. I also have a habit of breaking my cross strings before the mains are showing any major wear. My string history with these racquets is as follows. I first had a string job of all luxilons (not sure what kind or tension), and it was way too harsh on my arm. Next I tried a full job of Wilson Reaction 16 strings at 52lbs. I liked the way they played but the strings moved around a lot and I broke the crosses after about a month of moderate play. When the reactions broke, 3 different cross strings were very frayed and about to break, while the mains were relatively fine. Finally, I tried a hybrid of Luxilon Alu Big Banger @ 54lbs in the mains and Babolat Xcel premium @ 57lbs in the crosses. I was hoping to get more durability from the luxilon mains while keeping some comfort from the babolats. I found I could swing a little harder than with the reactions while keeping the ball in, but the cross strings broke after about the same amount of time. Arm comfort was better than all luxilons by far, but slightly worse than all reaction. So this is what I was thinking about for my next string job: Mains: Technifibre Biphase X-one 16 @ 56lbs Crosses: Topspin Cyberflash 17 @ 53lbs I'm considering putting the cyberflash in the crosses since I seem to wear them down faster for some reason. It's also my understanding that the main strings will dominate the characteristics of the string bed, so I will get the most comfort possible out of the technifibre. Do you guys think this is a good idea? Will this last longer than a whole job of technifibre? Thanks in advance for any advice.
