the heil stuff is really great, lots of folks are going to their camp at the moment. as stated, it definitely comes down to the individual voice and how each mic reacts to that voice.
funny how proximity used to be considered a bad thing, with over emphasis on lows being to outcome...
now, due to the nature of the beast (the marshall stack, for example)
mics are being designed for this purpose.
i'm really into the beyerdynamic stuff right now, despite having a nice selection of sennheiser mics available for free through tour support....
i find the m88 is the shizz with all 3 female vocalists i mix for,
and the heil, sennheiser and sure mics just didn't cut it for them.
i've used different condensers including the 105 as well (i find it picks up a hell of a lot of stage sound, like most condensers), but if you visit a couple hundred different places a year with different systems you might find that vocal condensers can be problematic.. one bad connection or slight short in a cable can ruin your day pretty quick. you loose an overhead on the kit, not many will notice... you loose the main vocal, everyone wants to kill you, including the artist.
i usually leave the condensers to stationary uses...
anyway, glad you found one you like jimmy!
