hypers are good for many uses.
Far field recording is one use, say you are taping from the lawn at a outside shed with no relay tower..hypers or shotguns for that matter come in handy, would even conisder using them under the shell of certain outdoor venus that have that boomy factor (I.E. Darien Lake) unless you are really close.
I use mine pretty much all the time taping in doors unless I am lip of stage or on stage. They are good for crappy sounding venus, cut down on room refection and some crowd noise, but watch out for the pick up pattern in the rear lobe.
Some hypers are different than others though...I find the mk41 to perform well in almost any situation, unless their is wind.
