I just finished selling the ARMS 17 mounts on a number of SF M962's to upgrade to LaRue. Ended up $23 out-of-pocket for each. The LaRue mount undoubtedly increased the resale value on the 9v Surefires. Scout lights are nice. I have one with a LaRue mount and one with the SF screw. With enough loctite, the screw mount is OK. It just isn't as good as LaRue.
