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
Choose the EZONE 98 2022 if…
All-court players, intermediate to advanced
Flexible — arm-friendly (RA 65)
Choose the Blade 18x20 v8 if…
Control-first players, flat hitters, serve-and-volley
Very flexible — max comfort (RA 60)
🎵 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.
Blade 18x20 v8
Very flexible frame (RA 60) — 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 Blade 18x20 v8 (SW 327), add 7g of lead tape at the 12 o'clock position on the EZONE 98 2022. This raises its swingweight from 318 to approximately 327 kg·cm².
