pros and cons of making use of VTK interactor/interactor styles vs making
my own "tool system" for interaction.

Ah, I see.

whether you make use of QVTKWidget, or if you have your own such class?
Because looking at QVTKWidget (which I currently make use of), it seems to
force a VTK interactor to be set on its rendering window (if one is not
provided, it will create one).

felt that I needed total control over the QT<->VTK connection which meant
writing my own class.  I wanted something minimal so that I'd be able to
fix problems quickly.

Alright, that makes sense then. I'll see how I'll proceed. Thanks for
