Dunlop aerogel 2 hundred plus 16X19 Can not find the stringing pattern for this racket? Not on Klipper? My doubles partner's racket. 61 year old male. Old school. Hits mostly flat but does hit some top spin. Turns the ball beautifully down the line. Controls the ball well. Serves with pace. Uses Prince synthetic gut duraflex 17 @ 60lbs CP now. Uses it untill it breaks. Doesn't believe strings make any diference. Want to introduce him to some new strings. Doesn't want to spend a lot of money. Any string suggestions? Thank you for your help.
