Does anyone have any experience/thoughts about using a gimbal mount such as a Wimberley WH-200 Gimbal Tripod Head. http://shashinki.com/shop/images/WBL-WH200-02.jpg. Photographers use them to control large 600 to 1200mm 15 pound plus telephoto lenses. Properly set up they allow the user to easily control the attitude of the lens with one finger. Leaving aside the bulk, weight and price of the mount, approximately 3 pounds 3 ounces, and about $600, it would seem to be a good way to control a heavy gun on a tripod. Combined with something like a Hog Saddle it would seem to be better than a ball head mount. Clearly the bulk, weight and price are issues, but leaving those aside I am interested in what people think about the idea? I am considering buying one and trying it out.
