TAv mode — do you use it?

If you want to shoot wide open in TAv, you might as well use Tv mode with auto ISO. That way you won't get overexposure in Tv mode, as the program line will just stop down for you if it hits the lower ISO limit and otherwise the behaviour will be identical, i.e. wide open aperture at elevated ISO values.

On the other side, I suppose it's an advantage of TAv mode to be able to stop down quickly just by twiddling the rear (aperture) dial, as opposed to turning the mode dial from Tv to TAv and then twiddle the rear dial.
