Davec Your talking about rubbing points what the difference if the cam rides on the limb or on a nylon or teflon washer.I bet the there would be less friction on the side with the washer.Also I'm talking aboutone washer not 4 I don't know were you got the idea about 4 washers.I had one installed one the left side of the cam (right handed bow upper cam)which gave my cam just enough room to rotate.Good luck with getting your bow fixed.And like I said before if bowtech would of had installed a washer from the get go we wouldn't be having this discussion right now.
