eh it’s mostly a luxury for me i don’t really use my platen as much as i’d imagine most people do. 70-80% of my work i do on the wheel since i grind the same way tim hancock used to teach. But having something that guarantees i don’t have to worry about wear and reflatten the platen periodically is a very nice thought. But i gotta see if it’d even fit on the tw90 stock platen or if i gotta make a new backer for it since the tw90 platen is hollow ground on the back and extends past the bottom of the idler wheels which limits the amount i can adjust it in to compensate for the added thickness of the carbide
