f anyone states that a compound radius causes buzzing, then they simply don't understand the geometry of the issue. Each string travels its own path to the bridge saddle. Getting these frets level to each other along that path is the goal in any fret level. Some techs have radiused leveling and sanding blocks that they try to use on compound radiused necks which is a mistake. You just have to know the animal you're dealing with and use the right methods and tools for the job.
My thoughts exactly. You're not after a cylinder (ala straight radius), its a cone. Radiused blocks can create dead spots (or worse) on compound necks, those are best left to straight radii. You should level side to side to follow the compound curve or at radiused angles from the nut. My Tele doesnt buzz at all and its got fairly low action.
