I have read several very good reviews about Kinlin rims. Since you already have the wheels built -- it is cheaper to change brake pads than rims. Nobody is going to say negative things about Campagnolo (except maybe Syncro shifters). I like their brake pads alot. I like them better than Shimano although I think Shimano pads are softer and help stop you faster. My rims stay cleaner (less brake pad marking on rim braking area) when using Campagfnolo pads. If you do not like the brake pads already suggested then get some new Campagnolo pads. Throw away the NOS pads.
