With a setup with 2 screens (or more) you can have a PFD on both screens and select which AHRS (in a dual GSU25 system) to display, so you can view both AHRS and the G5 simultaneously. In my case I switch the pass display to PFD mode and select AHRS 2.

Personally I would never trust the TT in IMC, they have a history of internal gyro tumbling resulting in suddenly misbehaving AP.

I have three independent AHRS systems. G3X/GSU25, G5 and also a sentry with Ipad. I could safely exit IMC with any of these. I have not had a single issue with any of the units so avionics failures aren't at the top of my list of things I worry about. I could eliminate one of the backups and still have double redundancy. I do think we go way overkill on what has turned out to be a very reliable system when there are more vulnerable single points of failure in the system.
