Lids are like the slowest of the slow, they have that in common, generally b/c of the absence of a bevel. You don't see beveled or rounded edges on jar lids, hence the name. Old timers will scoff and say that only superclass, wide diameter lids are the one true lids but that's just because they preceded golf discs and lid shaped golf discs. That's really annoying b/c Rattlers, Sonics, and Polecats fly a lot more like Zephyrs and Ultrastars than they do Aviars, Rocs, or Teebirds. But some guy in nuthugger shorts and a tie dye shirt couldn't play catch with a Polecat on UC Berkely's quad back in '72 so it can't be called a lid.
No, do they have JB Rattlers? That'd be nice.
