Justin.
Your layout looks as if you put lots of thought in it...Well done. Always remember it needs to fit your needs and it is your panel you will be flying behind.
I just finished my IFR and thought would share my experience as to configuration. I have AFS and ifd540, sl30. Grt mini, and everything that goes with. My instructor flew behind the latest competitor panel recently before doing my training and he was very impressed with our setup. I am not saying you should change manufacturer but at least look at them all to get more confused

in our experience the IFD540 ( which is not 14k) along with AFS is a incredible package. But better yet....And this is where we see the value..The team at AFS lead by Rob H is the best there is by far...Their support has more value than the hardware itself. Flying IFR in IMC is not for the faint hearted...For us we could not have chosen a better package. Just my opinion...Good luck going forward
