PTFE feet on smooth hard pads vs ceramic feet on textured hard pads: Smooth hard pads with PTFE win for consistent glide

Smooth hard pads with PTFE feet give low, predictable friction, while textured pads catch PTFE and make micro-adjustments inconsistent. Ceramic feet are harder but have higher initial friction and feel scratchy on textured surfaces, amplifying chatter. For reliable glide, stick with smooth hard pads and PTFE; save ceramic feet for glass pads where they actually shine.
