I could never get the erasers to work well and just gaff tape them to things- telescopic spacer bars, striff wires, walls, floors, people, other mics..
Don't overlook the super awesome magic power of boundary-mounting them! it's one of their most effective skills. Just taping them to a hard surface works, but the DPA rubber boundary mount adapters help protect them. I'm totally serious about this..
Right now I'm listening to a 6 channel surround recording from last Thursday made with four boundary-mounted 4060s and an ORTF pair of Gefell cardioids. Jazz trio, no PA, seated crowd, 3 of the 4060s were gaff taped to the font face of the stage lip wall, spaced apart and facing out into the room as surround channels. The 4th 4060 was in the DPA rubber boundary-mount adapter and taped to the stage surface forward of the L/R pair, slightly closer to the kick and snare. If you could hear it now, you'd want to boundary mount 'em!
