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 2022 if…
All-court players, intermediate to advanced
Flexible — arm-friendly (RA 65)
Choose the Pro Staff 97L v13 if…
Control-first players, flat hitters, serve-and-volley
Stiff — more power (RA 69)
🎵 String strategy for each frame
These are different rackets — they deserve different string setups.
EZONE 98 2022
Balanced stiffness (RA 65). A mid-stiffness co-poly like Babolat RPM Team or Wilson Revolve at 52–56 lbs gives a comfortable all-court setup without sacrificing spin or control.
Pro Staff 97L v13
Stiff frame (RA 69) with plenty of built-in power. Use a control-biased poly like Luxilon ALU Power at 54–58 lbs, or a hybrid (natural gut mains + poly crosses) for extra comfort.
⚖️ Specs Equalizer
Can I make these specs match?
To match the swingweight of the EZONE 98 2022 (SW 318), add 5g of lead tape at the 12 o'clock position on the Pro Staff 97L v13. This raises its swingweight from 311 to approximately 318 kg·cm².
