I have searched the archives and can't find a definitive answer on whether the older red and black dippers are the same volumes or different enough to buy a set of the black. I have the new yellow and the older red. By the way the older red dippers have different dippers on opposite sides of each dipper on the two smallest ones. The #20 and the #39 have this feature which throw different volumes but aren't listed on the chart. Anybody have the red and black to make a comparison and let me know if they are the same? Thanks Oily
