[Lil' Lavery]

We tried a few surfaces briefly during prototyping, and liked our results with shelf liner. We later heard from a couple sources that roughtop tread worked better, but we didn't have any on hand to prototype with. By the time we acquired some (thanks 341!), we had already set the dimensions for our shooter. The additional compression on the disc caused by the difference in width between the shelf liner and roughtop tread significantly reduced our performance, so we ended up sticking with the shelf liner. If there was enough time to adjust our shooter dimensions, we may have had different results and gone with the roughtop tread.
