Sometime, to avoid noise and render faster, I set the bounces to 0, but then I don't get any reflection on water, glass, etc... I know some nodes provides test to stop a ray (like "is camera ray"). Can I get the best of both worlds  : no noise and reflection ?

I thought of controlling how many bounces a light path makes with nodes or python depending on what kind of materials it hits ? Like get +1 bounce if glossy or so.
