I’ve never had a racquet so capable at the net than the ezone.
I demoed each (Vcore 98 2018 tho) for a two week period in mid/late November. I agree that the Ezone is easily the best volleying racquet I've ever used, even better than my outgoing Phantom 100 with its very round head shape. Felt like every volley I hit was solid and that I hit the ball in the center all the time. The Vcore was average on volleys.
I thought the Vcore was considerably more powerful than the Ezone on groundstrokes and serve though the sensation of hitting a big serve was more satisfying with the Ezone. If I had to assign numbers, the Vcore is a 9/10 on power and the Ezone a 6. Even then, I didn't think the Vcore was a rocket launcher.
The launch angle between the two was noticeable with the Ezone being much lower. I'm used to a higher launch angle.
I didn't think the Vcore was any stiffer than the Ezone. I strung both with VS/PTStrike.
I ended up going with the Vcore to replace my Phantom 100 because I was after more power and there was a Black Friday sale. Removing the price, I still would've gone with the Vcore.
