🎵 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.
Black Ace (315)
Very flexible frame (RA 56) — 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 Black Ace (315) (SW 325), add 18g of lead tape at the 12 o'clock position on the Clash 100L v3. This raises its swingweight from 301 to approximately 324 kg·cm².
