I haven't!
I have some I always go back to, but I think I just love trying new ones too much to use the same tube over and over! My current faves are Bobbi Brown Party Mascara (it's a party on my face?), Makeup Forever Smoky Eyes Mascara, and Too Faced Better Than Sex (*blushes while typing*). Full disclosure: I have multiple mascaras in my makeup bag because I like to do different eyelash "looks" from time to time...
Tell me what your HG of mascara is!
