Bracket alternative
 

Search the net for the Bracketron RWA-201-BL, it is designed for GPS's on golf carts but works just as well to hold my FS-200 Pro's to the handle of my XH A1 and A1s the clamp is adjustable enough to fit on pretty much any tripod leg. Better yet you can get them for about $12.00 plus shipping. I bought two for less than half the price of the "offical" mount.
The other great thing about these is the bed for the device has tabs that support the bottom of the FS, plus the sides can be extended out and even split to make a longer wall plus they have good quality dense foam rubber embedded that will not let go of your device easily.
For around $30.00 bucks you can't go wrong.
