I’ve tried VZ thin diamondbacks, Scales 2.0, Lok Thin Bogies, CZ Thin Lemon Graters, Rubber SP-01 grips, and Lok S2-specific Bogies.
I settled on a pair of S2-specific Palm Swell Grips in Jayson’s Roughneck texture. Great grips and very aggressive.
If someone made grips with the profile of the Scales and the texture of the Roughnecks or Diamondbacks, they would be perfect.
