cocolos, not avionics related, but you're lucky enough to be not far from Chris Zavatson...one of the most prolific contributors to the Lancair community. You might want to consider his plenum configuration and the mods he's made to the landing gear system to improve the reliability (both are quite simple).
fwiw, I have a 360 and have a standard 6 pack with a Garmin 420 (used to be a 430 2 owners ago, but they swapped it out for a 420 then sold the airplane and used the 430 in their other plane). I fly it IFR most of the time and enjoy it a great deal.
I'm not suggesting you replicate my ancient configuration, I know glass is the way of the future, for better or worse
Just letting you know that there is another IFR 360 out there if you ever need to talk.
