But the 2 instruments measure different things. The yawstring (in 
theory) measures airflow angle at the fuselage. The inclinometer 
measures the difference between gravity and the opposite centripetal 
force - when in balance, the ball is centered.

The question is, which is a better measure of coordination? Or, IOW, 
which is more im****tant? Because of the difference in drag at the 
wingtips during the turn, the nose may yaw away from the center of the 
turn. The yaw string would show that, while at the same time, the 
inclinometer would be centered. I understand that some believe that 
that's the way it should be. Others believe that you need to hold rudder 
into the turn to minimize the drag.

I should experiment in my LS6. Lord knows that I'm tired of looking up 
at the gaggle :-).
