Shawn, I only realised the existence of inherent sideslip when I read your Cyclic and Collective book 15 years or so ago but it seems to me you have a choice:
fly wings level ball in the middle and accept you are sliding sideways gently through the sky and the heading will change or
fly the string in the middle with a little AoB and maintain a heading
In the Gazelle, as I am sure you know, we used to teach the string below 90 kts and the ball above.
