John,
Thanks for your comments. If you notice in my original post, I did state that it was for 20-22mm mics only. Obviously the lyres are made specifically for the shape and weight of specific Røde mics, but if you happen to have a different mic that fits those parameters, would it not likely still work just fine?
That's how I came to choose the 62-shore lyres for my DIY mounts for Line Audio CM3s. At that time, Rycote did not have the CM3 in their "my microphone" application listing. I saw that those lyres were recommended for Sennheiser MKH 8000 series, which are a similar weight and size to the CM3, and as it turned out they work perfectly.
Maybe what put you off was my saying "Rycote equivalents". You're correct that the INV mounts are more flexible over a broad range of products, one of the biggest benefits being swapping out lyres of various stiffness as needed as I personally found so useful.
