URSA Mini Foamies have been designed specifically for smaller diameter microphones. These include the DPA 6060, Sennheiser MKE1, Countryman B6 however they also fit well onto Sanken COS11 mics. They are also best suited to be rigged onto the tip of an antennae of your transmitter, this can help reduce the RF loss you can get when an antennae is pressed against the body.
