RA Stiffness — lower = more flex & comfort
Weight — higher = more stability

🎵 String strategy for each frame
These are different rackets — they deserve different string setups.
Speed Pro 2026
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.
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 Speed Pro 2026 (SW 328), add 2g of lead tape at the 12 o'clock position on the Black Ace (315). This raises its swingweight from 325 to approximately 328 kg·cm².
