I am using original Ultimaker PLA: 210 on the head and 60 on the bed. I know about my elephant foot issue and I just cut it down with a surgical razor (the really sharp ones used in surgeries - I like them more then a traditional hobby knife) or sand it a bit. I can lift it off the bed slightly but then I am affraid of poor adhesion. Once I figure out what is causing the nasty support stringing I will tell you all. I have seen it in many prints on different printers. Next time I might try using "concentric" supports (in Cura 4.0).
