Been demoing both and like them both very much, Vcore very comfortable with any string (important to me), Ezone comfortable enough with Multifiliament, not as much with polyester. Ezone maybe?? a bit more power, Vcore a bit more control. Ezone a bit more fun, better cosmetics to me in either color, but maybe not as predictable as Vcore. I could play with either one. I'm 4.0 in my 60's. Old school for the most part, but working on adding more spin and kick serve. Currently using DR 98+, very comfortable, SW just a bit too high for me although trimming the head guard helped a bit. Sometimes feel that maybe the SW and length make it tough to control, so that is why I am considering Ezone 98 and Vcore Pro 97. Would appreciate anyone's thoughts. Thanks!
