Lifelong Yonex user here. I currently use the RDS003 (love it!) and am looking to "upgrade" to a newer Yonex offering. On a whim, I purchased the EZONE 100, but don't love it. It just feels like a night and day difference to the RDS003, IMHO. The EZONE 100 just felt too bulky and thought it lacked the control and spin access of the RDS003. Any suggestions??? I see a few new models (VCore, EZONE Xi) available, but I thought I'd ask for advisement prior to ordering a slew of demos. Thanks - much appreciate the feedback!
