Donnay Pro One GT 16×19

The Pro One GT is the sister to the GT 18x20 with notable differences. First of all, the overall weight of the frame is much lighter at 10.19 oz compared to 11.11 on the 18x20 frame. This one is also stiffer at 59 compared to 50 for the 18x20 model. Swing weights of the two models are quite comparable so in the 16x19 model you'll immediately notice the overall weight difference. So, if you're a Babolat person and you're looking for a lighter frame with a standard 16x19 pattern in the Donnay line the Pro One GT 16x19 is a good choice. Both Pro One's offer Donnay's Quadcore™ technology so the comfort remains and the solid overall feel is exceptional.
