Correct me if I'm wrong but using an omnidirectional mic would just make it easier for it to capture noises and other stuff that would ruin my recordings.
You need to understand the physics...
The cardioid has a ratio of 1.7 - this means that a cardioid at 1.7 metres will pick up the same sound as an omni at 1 metre.
Also an omni does not have any proximity effect, so you don't change the character of the bass as you move the omni closer to the source.
Also, the omni has a good octave more at the bass end compared to a directional mic.
Yes, I have mics of all patterns in my kit, but I do seem to use the omni most of the time.
