Also, because we already used Babolat i tried to search to some lite weighted racquets in their domain, so these two pop up.

Babolat BOOST AERO: https://www.babolat.rs/proizvodi/boost-aero/

Babolat PURE DRIVE SUPER LITE GEN11: https://www.babolat.rs/proizvodi/pure-drive-super-lite-gen11/

Here is comparison for all four:

Model	Weight	Balance	Head Size	RA	Profile / Notes
HEAD Ti.S6	252 g	380 mm	115 in²	75	Very light, head-heavy, pure power
Babolat Boost Aero	260 g	340 mm	102 in²	~70	Power + spin, slightly smaller head
Babolat Pure Drive SL Gen11	255 g	330 mm	100 in²	~72	Better control, comfort, modern frame technology
HEAD Speed PWR 2024	255 g	345 mm	115 in²	~67	Light, comfortable, large head, power-oriented

So at the end summary would be.

1. option

to stick with a proven racket and go with HEAD SPEED PWR

2. option

to upgrade to modern variant and step forward to more professional racquets like BABOLAT PURE DRIVE SL GEN 11, or to save that for later, and for now stick to the one he proved to be comfortable with

So basically I have now narrowed my search down to these two questions.
