Side-by-side comparison using independent TWU lab measurements
ℹ️ Different head sizes (98 vs 97 sq in) — this affects power and forgiveness independently of the other specs.
Aggregated spec scores
Scores calculated from TWU RA, weight, head size and string pattern.
Lab data comparison
Measurements from Tennis Warehouse University (TWU)
RA Stiffness — lower = more flex & comfort
Weight — higher = more stability
Swingweight — higher = more plow-through momentum
Head Size — larger = more forgiving
Choose the EZONE 98 Tour (2025) if…
All-court players, intermediate to advanced
Very flexible — max comfort (RA 62)
Choose the Percept 97D if…
Arm-sensitive players, comfort-first
Very flexible — max comfort (RA 62)
🎵 String strategy for each frame
These are different rackets — they deserve different string setups.
EZONE 98 Tour (2025)
Very flexible frame (RA 62) — arm-friendly. Pair with a crisp co-poly like Luxilon ALU Power Rough at 54–58 lbs to add control and prevent the string bed feeling too elastic.
Percept 97D
Very flexible frame (RA 62) — arm-friendly. Pair with a crisp co-poly like Luxilon ALU Power Rough at 54–58 lbs to add control and prevent the string bed feeling too elastic.
⚖️ Specs Equalizer
Can I make these specs match?
To match the swingweight of the EZONE 98 Tour (2025) (SW 335), add 5g of lead tape at the 12 o'clock position on the Percept 97D. This raises its swingweight from 329 to approximately 336 kg·cm².
