Today was the first time I played with this combo (strung at 48 lbs). I'm a bit bipolar on these strings. They are severely stiff, and are highly underpowered. I can appreciate the lack of power sometimes, but there are occasions when I could use a little more juice. These strings are very demanding. I have to put it my full effort into every shot to truly bang some heaters. Otherwise I hit balls that are basically sitting ducks on the other side of the court. Will they get a little softer and more playable with time?
