late to the party, but as others have implied, a larger diameter hollow tube is stronger than a smaller diameter solid bar, of the same mass, because leverage.  not sure what diameter tube you have, or how big your clamps are, but an over tube would definitely be more helpful than an inner bar, if your clamp can handle it.  even a tight wrap of kevlar tape could help.  remember that the difference between a tube bending and folding is the sides blowing out.

@CanonFanBoy - I know exactly what you mean.  I own a 7' umbrella, and I love it, though it is often too awkward for me.  I often use a 48" umbrella or a 60" rear-illuminated bowens mount softbox (like an octa) instead.

Most of the time when I'm using the 7' umbrella, the shaft is parallel to the ground.  In this case, an easy work-around is to use another light stand behind, with a Magic Arm (articulating joint + clamp) propping up the back and releiving it of any stress.

Another possibility is to use a large clamp to hold the umbrella, like the one pictured at the end of the boom here:

The reason being, this holds the shaft solidly over a wide clamp that is a few inches in size, instead of gripping it by a small (tiny) surface area as with a strobe or umbrella/flash holder.

Great idea Talys. Thanks!
