These rubbers suit very different playing styles. Tenergy 64 is the fastest Tenergy, spin-insensitive and easy to block and counter with, plus light and versatile on either wing. Its low throw and unforgiving passive receive ask for an angle adjustment.
The Yasaka Rakza Z is a tacky hybrid built for extreme, low-slip spin on loops, backspin openings and serves, with a surprisingly high control and long dwell time for a hard rubber, plus a strong linear kick when you commit fully. It is heavy and can cause arm fatigue, has a high throw, and is weak at less than full power or when out of position.
Go with Tenergy 64 if you want fast, spin-insensitive, versatile play and easy blocking. Go with the Rakza Z if you are a proactive forehand looper who wants to pressure opponents with heavy spin and placement and is happy to swing fully, or want a cheaper tacky hybrid in the style of Dignics 09C or boosted Hurricane 3.
