One thing I noticed at the table: the wedgetop tread sitting out looked appreciably thinner than the stuff we've used in the past from McMaster-Carr. Is it from a different source? Would the McMaster belting still fit? I suppose it's a moot point for us, since it took a year and a half (and some 25 competition matches at two events) to throw a single tread on our much-loved (and, admittedly, much-abused) 2007 robot, but you never know when you'll need a new tread in the middle of nowhere*.

*Or, as I found out while trying to find a 3/16" rivet and rivet tool at Brunswick Eruption last year, in the middle of New Jersey!
