that's where its touching in theory. and i believe my hoyt cams had sealed bearings, and a teflon spacer, and bowtech used spacers in the past w/ sealed bearings. doesn't mathews use sealed bearings too, anda spacer? not sure. anyway, i'm not sure that's the reasoning or use for teflon washers anymore. are you sure about it? and, really, the limb caps are just a cheap plastic substitute if they aren't just cheap plastic. i'm not saying anything about bowtech - just that to my knowledge that post wasn't quite jiveing - and i'm happy to be corrected.
