I have had my Butter Rugs for awhile. I haven't tried much else.. Most of what I have tried has caused too much drag. I'll usually keep a butter rug on my "scratch" table and a picture slipmat on the other.. Nothing wrong with switching up or getting a new picture slipmat. I actually just came across a pair of Stanton Focus Aerodynamic Slipmats, so I am now giving those a try. It's been awhile since I have switched it up, esp on the table I mostly scratch with. If I hadn't come across these I most likely would have stuck with Butter Rugs.
