Currently have my two Pure Drive Cortex racquet strung with Yonex Tour Super 850 16g crosses and WeissCannon TurboTwist 1.24 as well as Signum Pro Tornado 1.23 mains...tension 58/60. I went with these two mains because of the great reviews and to soften up the 70 stiffness rating of the racquet. Love the soft feel and spin of both strings but find that the strings along with the Woofer/Cortex combo make the string bed feel a bit too soft...never thought I'd say that considering the racquet has a 70 stiffness rating. I'm wanting to make the stringbed a bit more firm so I can feel the ball a little better on the strings (a bit too plush right now) for dropshots and control without losing the incredible spin and depth I'm getting with the racquet right now...and I definitely don't want to go so far as to start having elbow problems. I'm considering going to a slightly crisper cross string (Gosen OG Sheep Micro or Forten Sweet) to see if that gets me the feel I'm looking for in the racquet. If that doesn't work, is my best option to look for a slightly stiffer poly/co-poly (maybe Lux BB ALU or others...any suggestions?) for the mains or to just increase the tension of the strings I'm currently using in the racquet? Thanks for any and all input. TripleB BTW: of the two main strings I tried, right now I would say I prefer the Turbotwist. The Tornado plays a bit softer but I think the Turbotwist offers just as much spin, offers better control, slightly better touch, seems to move around less, and overall I just played better with it than the Tornado.
