Not a waste. I will be getting some too. I dont want my heel digging into the floor to mess up the flooring when I can have a mat take the hit and replace as needed.I ordered a BL with MGV, so I will have the rubber washout flooring. I also ordered the rubber floor liners. Was that a waste of money or is the additional redundant protection worth it? Are most people with washout flooring ordering the floor liners?
