Donnay Formula OS EXT

The Tech
Most racquets are hollow, but this 9.9-ounce model is injected with tubing to produce a light, shock-absorbing, solid-core frame.

Leach's Take
"I felt like I was driving a Cadillac. It's smooth, easy, and perfect for anyone with shoulder or elbow pain." [$200;]

Best For
Tennis elbow.
