Chrish, personally for me , I would be looking at the fat cap , and the amount of color the ham has , the browner the better IMO , are you loooking at leg hams or picnics ? are they whole or cut ?? as far as the fat cap, the leg hams will be thicker than the picnics, you should be able to tell about how thick it is by looking at the rind , where the meat has been seperated by the butcher.
