I have owned 3 G11s and 4 GM8s and with each of these mounts I have always made sure to include this upgrade. Why you ask? The answer is simple, These are great additions making the grip and rotation of each clutch easier to manipulate ( I also like the way the look, Beefer). Naturally, you can keep the stock knobs but I highly recommend you step up and buy a set of these Babies, YOU will love em! James Edwards Elk Grove CA

This addition makes my GM8 much easier to use. I can find and tighten and loosen the clutch easier in the dark. Highly recommended.

However be advised that they dont work as well at high latitudes. Up here in Anchorage, Alaska, 61 degrees North, the handles run into the mount. I had to remove two of the three handles once it was screwed down to the correct tension and then jacked up to my latitude. The remaining handle works for adjusting clutch pressure. Too bad I cant use it as it was designed however! -Christopher Erickson
