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 Blade 98 16x19 v10 if…
Control-first players, flat hitters, serve-and-volley
Very flexible — max comfort (RA 61)
Choose the Pro Staff 97 v14 if…
Control-first players, flat hitters, serve-and-volley
Medium — balanced (RA 66)
🎵 String strategy for each frame
These are different rackets — they deserve different string setups.
Blade 98 16x19 v10
Very flexible frame (RA 61) — 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 97 v14
Balanced stiffness (RA 66). 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.
⚖️ Specs Equalizer
Can I make these specs match?
To match the swingweight of the Pro Staff 97 v14 (SW 332), add 7g of lead tape at the 12 o'clock position on the Blade 98 16x19 v10. This raises its swingweight from 323 to approximately 332 kg·cm².
