Head Graphene 360 + Gravity Pro
The Gravity Pro is the racquet all 18×20 players have been waiting for!
Why? Great weight, and excellent swing weight right out of the box! For players that think the Prestige models are too stiff, (they are not), this model will provide feed-back that the Prestige damps out through the cap system.
Big hitters will benefit from the 18 x 20 string pattern when going for the “flat, down the line” shot.
You will see all the specifications later on but now let’s talk about the reaction to the binary graphics package that is used on all the Gravity models. One side is Lava, and the other side is Miami Green ( my description) which makes for an exciting pickup reaction!
The excellent stiffness of RDC 60 combines with the dense string pattern to yield an effective stiffness of 30.7.
Now for some fun!
