I had to install four, using the one closest to the horizon

This is the current German 15m-champion's opinion about the
sensitivity of a yaw string:
Even with a significant sideslip angle it's better to let the glider
straiten itself (rudder centered) instead of using rudder all the time
to keep the yaw string centered precisely.

In his opinion the deflected rudder produces more induced drag than a
moderate yaw angle (=up to 20 degrees yaw string deflection).
In my opinion success proves him right.
