Since glass pretty much my endgame, I'm trying to find other fast, but durable, surfaces to try out. UHMWPE is harder than PTFE, and apparently HDPE as well. If I could find a piece of it that isn't curled, I could try texturing it myself to get a smooth glide (idk how though), as sheets of this stuff almost always come smooth, with or without scratches.
Unless someone else has already done it and determined it's crap.
