Just finished watching the video.Tennis HQ says he has been feeling arm and wrist soreness with EZT. Not sure what everyone's experience has been.
In his last detailed review on EZT, he mentioned he had tested it thoroughly for several months. There was no mentioning of arm and wrist soreness in that review .
The mistakes he made were he praised EZT very highly and he announced he had switched to it. Playtesters do not do that . Playtesters help to market and sell racquets (not just one racquet). Every racquet is good (or interesting and worth demoing). They usually say : each racquet has its own merits ... if you like this play style, it will suit you ... if your level is "beginner to intermediate", this suit you ... if your level is "intermediate to advanced", it will suit you ... I may switch to this racquet ...
But for sure, Lynx Tour @ 55lbs may lead to a stiff stringbed (not good for the arm under the conditions of hard hitting and frequent play).
I string Lynx Tour @ 50lbs.
Just another note. Vcore 98 and Ezone Tour 98 are for different levels of players. A review/battle of Vcore 98 vs Ezone Tour is pointless and unnecessary.
Vcore 98 is easy to use, beginner to intermediate level
Ezone Tour requires players to possess certain skills and techniques, advanced level
