QUESTION: Neckstrap design for heavy cameras

Hey, all.

I have a Canon 30D with a battery grip, and just ordered a 70-200 f/
2.8L IS lens.

I'm a little concerned about the overall weight of the setup. I've
currently got a 70-200IS, and with the camera and that lens hanging
around my neck I start really feeling it after only a little while.
It's the pressure the strap puts on my neck that kind of adds up after
not too long.

It occurs to me that some kind of little harness setup, with straps
hanging around a person's shoulders instead of around their neck,
might make for an easier way to sling the camera while wandering
around.

I've also heard of folks jamming the tripod hook under their belt, and
hanging the whole setup off their waist.

Curious if anyone else has had any brilliant revelations to keep their
necks from getting strained from carrying that kind of gear around.

Thanks,

BD
