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
Choose the Clash 100 v3 if…
Arm-sensitive players, comfort-first
Very flexible — max comfort (RA 54)
Choose the Astrel 100 if…
All-court players, intermediate to advanced
Medium — balanced (RA 68)
🎵 String strategy for each frame
These are different rackets — they deserve different string setups.
Clash 100 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.
Astrel 100
Stiff frame (RA 68) 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 Clash 100 v3 (SW 308), add 8g of lead tape at the 12 o'clock position on the Astrel 100. This raises its swingweight from 297 to approximately 307 kg·cm².
