I had the racquet strung with Velocity 17g at 52lbs, (1.25 , 23.5kg) natural at the "
insistence"
of the stringer. I'm very happy with it.
-much easier on my shoulder, though still some tenderness due to the existing issue
-very good control and spin
-low powered.
It is somewhat similar to the Gravity MP I demoed with Head Hawk Touch, (a polyester) 17g, 51lbs which was very painful for my shoulder. And the Velocity is still better than the Technifibre Triax Fusion 16, 52lb for me.
Next time, I will try 16g.
This is a very helpful forum.
