Trying to choose a mount is always the hardest thing for me to do. I was looking at the new McKenzie 6900 / 9900 upright series mount. Has anyone seen it yet? I have a 152" mainframe 10 that is perfectly symmetrical. Any thoughts on how to show off that symmetry? Most all my other mounts are semi-sneaks. Any thoughts on the new 6900 / 9900 series mount is appreciated. Thanks!
