I got those from Shiningbeam holding my MG X Thrower. The Twofish lockblock bounced to much because of the larger reflector head. It is a very solid mount. One disadvantage of this mount is that it not as easy to remove the flashlight off the mount as compare to the Lockblock. If the battery cap is much larger than the body of the flashlight, you will have to remove the cap before sliding the flashlight off. Otherwise it is also harder for someone to just take it off since I usually leave my lights on the bike when I lock it up. If interested, I can post a picture of this mount later today.
