Quick question, when mounting a larger reflector (in my case an 8" F6) is there any hard and fast rules about how far apart the tube rings go which obviously dictates what bar you put it on.

It's a fairly long tube so I would imagine you would want a good spacing for stability and then put it on a long bar.

But really, I'm not sure how it's generally done.

Anyone?
