I was thinking that I would like to perfect the universal puck a bit more. So the bottoms that it is designed for are mostly rough surfaces and small to medium tiles. I like the slider, so I can play with the diameter of the slider and shape of the outside of the puck. I can provide what dimensions that it currently is if someone wants to know.

The dutch used to have a heavy square puck with a slider and a radiused edge, I like that but it worked better on large tile bottoms. Any input?
