I understand that an AHRS, compared to a Truetrak, is going to produce more consistent results in the hands of a trained and current pilot.

But will the AHRS require more training to use and stay current compared to the Truetrak? And not being a power pilot, I've zero experience with a panel mounted attitude indicator. My tactile attitude indicator is stick position fore-aft.

Seems like (after a few hours of IFR training) I could practice using the Truetrak and ASI in my routine VFR thermaling. And Kirk mentioned the desirability of a large AHRS display... I only have space for a 57mm display in my panel.

Seems like the Truetrak would be the clear best bet for me. The visual simplicity is intuitively appealing. Am I missing something?

I understand that an IFR-rated pilot would want an AHRS in a glider, but that is not me.
