Replacement for Voltric Z Force 2?

Hey guys, I have a brother who recently and previously used the Yonex Voltric Z Force 2, but he broke both of them . As you know the Z Force 2 has been discontinued for a while & difficult to get ahold of.

He told me that if he got a new racket, he wants it to be lighter than the ZF2. I assume a bit less head-heavy, yet still head-heavy is what he means.

As for the specs he used before he broke it, it was a 4UG5 ZF2 strung w/ Exbolt 63.

Any brand or recommendations, please? I would appreciate it. Please recommend rackets that are similar to the racket itself & info is given.
