I have several different one's from 6'-14'....Most of mine are all home made that I use all the time, I have one that my father in law uses and it is store bought. It is really difficult to put together (bolts, wing nuts, and crossbraces). I also have a couple that are made by gametamer, those are the only ones that I have that are store bought, the gametamers are the only ones that I have hunted that I would recommend. They have adjustable legs to get them perfectly level and they don't have all the braces that take forever and a tool box to put together. http://www.gametamers.com/brushtamer-pods-c-3.html They aren't cheap but they are the best IMO, of all the tripods..

I pick the height of my tripods by determining how tall the brush or trees are that will give me adequate cover thus resulting in many different heights that I own.
