AFAIK, no one (including me) is saying that a monopod is better a tripod for holding a camera in a single point in space. OTOH, a monopod (with folding support legs) provides a usable alternative in some situations. In tight spaces, like in a wedding crowd or on a narrow hill trail in Belize, it offers some advantages over a tripod.Exactly my point -- it has post-processing stabilization, so why even use the monopod in the first place? If you're going to sit there and let FCP and Smoothcam analyze and stabilize your footage, why not just go handheld? In many ways handheld is better than a monopod, it doesn't encourage the kind of motion that even Smoothcam can't really correct for later.
The OP's original question was whether he should bring a monopod along to a shoot along with his carbon fiber tripod. Some of us cautioned him that a monopod is not nearly as good as a tripod at stabilizing the camera and preventing unwanted movement that will look terrible. Some of us disagree, feeling a monopod is capable of good video. And some of us seem to consider a monopod with added legs a monopod when it ceases to be a monopod once the leg count grows larger than one. Those Manfrottos you referenced are actually tripods, Dan, regardless of what Manfrotto calls them. If they have three legs, they're tripods, and FWIW, I've tried those things and they're no better than a straight "still" monopod. They do not hold the camera firmly locked in a single point in space any better than a simple monopod, and that is what we're trying to do here, lock the camera at a single point in space so it doesn't move around while shooting video. The less movement, the better the tripod. The more movement, the worse. There isn't a monopod out there that can hold a camera as motionless as a good tripod, so since the OP is already bringing that with him, I would think the matter's settled. But alas.

Dan.
p.s. In addition to my two monopods, I have a Markins ball head on Gitzo carbon fiber sticks for stills and a Manfrotto 501 on heavy, no-name sticks for video. I understand and value a good tripod.
