If your going to be griding in skateparks, on wood, steel, or benches you dont need guards.
I'v been grinding all summer on my BMX, rodeo grinds, pedal grinds, feebles, double pegs, ice picks, smiths, evrything. And my pedals arent worn down, pedal grind plates are a solution to a problem that doesnt exist.
All they really do is make you slide faster on pedal grinds on materials like wood and skatelite.
