SO with that said: is this product 'restrictive'? I move and fidget alot, is there a button you could hit for a 'quick center' or someting like that for firing mode or for resetting where you are sitting?
When I get into the heat of battle I like to lean forward and othertimes when I'm tired I fly sitting and slouching.

In my profile, I use the ~ key to recenter the TIR which effectively "puts you back in center of cockpit looking directly front". I use this key because it's easy to get to with the thumb of my thottle-hand. I move around a lot too, while playing, and re-center my TIR at least once every couple of minutes unless in the heat of battle and I'm rocking and swaying when T&B'ing.
As long as your head is actually looking straight when you center the TIR, you're fine. Because you are telling the TIR what "looking forward" should look like to the reciever - if your head is pointed a little left when you center the TIR, it thinks that is what center is. Then if you move your head to the right, which to you, is "centered", the TIR thinks you're looking right.
Also, the POV hat buttons still work, so I hold the "look forward" hat button to semi-lock the TIR in forward view. I can still move my head around, but it the TIR input has now been effectively "dulled down" for those times when I need more precision for fine-tuning my aim. Works especially well when zoomed in for a long-range shot.
