Side-by-side comparison using independent TWU lab measurements
ℹ️ Different head sizes (100 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 Clash 100L v3 if…
Arm-sensitive players, comfort-first
Very flexible — max comfort (RA 54)
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.
Clash 100L v3
Very flexible frame (RA 54) — 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.
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 Pro Staff 97L v13 (SW 311), add 8g of lead tape at the 12 o'clock position on the Clash 100L v3. This raises its swingweight from 301 to approximately 311 kg·cm².
