🎵 String strategy for each frame

These are different rackets — they deserve different string setups.

Gravity MP 2025

Very flexible frame (RA 57) — 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 (300) 2024

Very flexible frame (RA 55) — 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.
