I’m 71 and have been using the Aero Pro Drive Plus for 10 years. Decided to get a new Pure Aero Plus to upgrade. Came strung free with 16 ga. Synthetic gut at 50 lbs. Played doubles and was hitting the ball so much better! My partner said that’s the best I’ve hit in weeks! All my shots showed improvement. The feel of hitting with the synthetic gut for the first time was amazing! I had more power in my shots and good control so I am very happy with my new racket and the gut strings. Anyone who likes hitting topspin and backspin will love this racket. I have played since age 14 and was considered a 4.5 most of my life. I learned tennis from watching Connors, Evert, Borg, etc. on tv. Have slowed down some with age but tennis keeps me “young.”
