I'm delighted by your excellent description of the version of lyre mount for the TetraMic.
I have added a page to my web site showing the result: <http://ambisonic.info/tetramic/rycote> Paul Hodges
I can see that sliding any grommets, split or otherwise, on a knurled stem is always going to be very difficult.
The only comment I would make is that though the microphone may be delicate the lyre elements are not. At exhibitions it is common practice to take a lyre and twist the insides round and round till the whole thing ends up as knot. They always survive and their shape memory brings them back to what they should be very quickly.
Actually, you can take the entire INV7 mount and hurl it a concrete wall, and it will survive, which shows that modern plastics can beat metal hands down - but do take the mic out first....
