No personal experience with the T-30, but I have worked with modern throat mics. You have to boost the highs like crazy! I don't have the documentation any more, but I remember like 50 dB of rise from 300 to 3500 Hz. With the right EQ, they aren't bad. However - even with these mics that I worked with, probably about the best in the industry, some people just don't come through well. There was this big fat guy who just sounded like mush. I guess if the skin is thick and floppy around the neck, the sound picked up there will be especially muffled.
There was some experimentation done with bone conduction pickup on the side of the nose. Also some experimentation was done with a "skull" mic, that picked up sound from bone conduction in the skull.
