The best is Gitzo. Period.
My best set up that is good for everything up to and including a 300mm lens is the Gitzo 1258 with a RRS BH40 head with a lever release.
I beat this thing and it doesn't even show the wear. I've skied with it, I've put it in fast moving trout streams 2' deep in water (freezing my butt off too), I've had it in sand, I've backpacked it, I've lugged it through airports. It is really amazing.
For example, in that trout stream I had a wake coming off of each leg. I was taking a 5 shot panorama and it came out so crisp and clear. You just know that the legs were taking a pounding from the water streaming past them, yet they damped out the vibration and made sure the camera platform was steady. Really nothing short of amazing in my book.
I'd recommend this combination as the sturdiest lightest weight combo that I know of - it weighs in at around 4lbs. Nothing else in this load range weighs as little.
Highly recommended.
Taking a step up, I'd go for the upcoming Gitzo 3540 with a RRS BH55. That is slighly more weight, but it will take a load of 39lbs. That is a ton more than I expect to ever put on it.
