Have an SR22 with glass - very nice for an experienced pilot who is good with avionics/computer systems/autopilots, or has learned to use them. Excellent for IFR, still handy for VFR but can make you keep your head in the cockpit and get behind/Lookout complacency...
For teaching VFR is a bit of an extra hurdle for students to get used to setting up.
I have even found so far, when teaching IFR = BAD...
Student pilots spend far too much time inside on a MFD when they should be scanning the PFD or looking outside for the airfield lighting @ Minima!!!
Learning not to Fixate on instruments is part of the training, but it seems to give them so much more to fixate on other than the AH!
Personally, I love it - when I'm in control!
..but when things go dark and pear-shaped; give me LRT's any day!!! Not enough backup instrumentation for IFR in an SR22 IMO..!
