I am using a 856-016 coarse diamond and wondering if I should be going over the prep with a 856 fine to finish. Also, are there any studies that show, on on a typical PFM crown, what kind of margin holds up the best? I am thinking , full chamfer vs say a shoulder with a bevel? I always do full chamfer. My new associate was taught shoulder w/bevel. Just wondering. Hope all are enjoying the Labor Day weekend. Mark
