If the Yonex 18x20 ends up being less than 325 swingweight or the stiffness is 65 or higher then I'll lean towards the Gravity Pro instead. I'm not sure I see the new Yonex 18x20 having a lower stiffness than the Gravity Pro. It'll probably all come down to swingweight really because the rest of the specs between the two are close. The 97 sq in of the Yonex vs the 100 on the Head don't matter much to me.The new Vcore will need to be softer in order for it to match the Pro.
