It is strong and angular. The listed flare potential is 4 to 5 inches, and the asymmetric RST Core + AI posts a strong .055 differential at 15 pounds for heavy flare and a powerful, defined motion. The polished U-R1 Pearl pushes cleanly through the heads, then makes a strong, angular move at the friction, later and sharper than the solid RST Hyperdrive. It sits at Roto Grip's HP4 performance level.
