THE ANALYSIS, IN CONTEXT

What this racket offers

Its reference ratings are led by power (9.0/10). The contrast is easy power (8.0/10), which helps identify what to compare first. A lower score within this profile is not automatically a weakness.

Strengths

Strong power for an attacking game.
Strong ball control for precise placement.
Very easy to manoeuvre when preparing the racket.

Materials and construction

The documented construction combines a carbon fibre frame, carbon 15K faces and a EVA Hard core. These names help identify the edition; playing ratings are considered separately because material labels do not provide a direct comparison across brands.

Your individual racket’s weight

The published range is 350–375 g. Check the individual racket you choose: either end of that range gives you a different total weight in hand, before adding your accessories.

Before deciding

Start with the attribute you want to change from your current racket, then check the qualities you want to keep. The figures help structure that comparison; the final choice depends on your priorities and preferred feel.
