I put my 7D with the 70-200 f2.8 IS on the Focus and I didn't have any problems with support. The thing with the gorillapod is that you might not be able to wrap the arms around a post or a branch with a large camera, if you decided to trust it that much at least.
If you have a really wide angle lens such as an 11mm, you can actually take a camera with this tripod and stick it on the hood of a car. Start pushing the car, open the shutter for a second or so, and then you will have a photo that makes the car look like it's moving really fast, when you only moved a few feet.
Sorry for the rabbit trail, just something cool you can do with this tripods.
