So I've narrowed my choice of upgrade to 3 different mics. Anyone with experience with either 1 of the 3 please help me decide? 1) Rode NTK - Amazing reviews. Not too expensive, but said to be one of the best vocal mics under $1500 2) Rode NT2A - 3 different patterns. The omni pattern looks especially fun. I've never recorded with omni, but being able to wild out w/o the loss of depth seems like a + 3) AKG C3000 B - Good reviews. Decent looking mic.
