I only use my tracking system in locked pit servers.
I find the mouse of more use with externals on.
Even on locked pit I find it equally easy to hold the base of my stick between my thumb and fore finger of my left hand and the throttle in the palm of my hand whilst I mouse view with my right hand.
When I need some extra authority on the control, or I need to fire, I swap my mouse hand over to the stick.
That probably sounds complex, difficult or unnatural, but I find it very easy.
I certainly never loose targets through disorientation.
I love my head tracking system, but that's mostly because it's more immerse, not because it gives any advantage over my mouse.
That said, if your less handy with a mouse, hat, or other viewing system, I can see head tracking being very, very useful.
I also love that it only cast me £10 to make.
