Anti-Slip Shelf/Drawer Liner Material???

[ChuckDickerson]

We are trying to decide what material to use for our ball conveyor. Yes I know, we are a bit behind. We are looking for feedback from anyone who has used the anti-slip shelf/drawer liner stuff in the past. It is light, seems pretty durable, and has good ball grip but how well does it hold up in competition? How exactly did you stitch the ends together? What type of thread or glue works best? Are the any pitfalls to look out for with this stuff? Yes, I did search CD and all I came up with is this, this, and this. We like it because it is cheap and readily available. You can get it at any local Home Depot, Lowe's, Wal-Mart, etc. Thanks!
