If you must order one of those, go for the one with shock-mounts.
Otherwise you can make your own, providing you have clips for the AT831s. Take a plastic ruler (or any scrap piece of thin plastic), drill a hole bang in the middle of it the size of the thread at the top of the stand, secure with threaded adaptor. The ruler will bend slightly when the stand is knocked, and provide enough shock protection. Trust me, thats my setup for open taping..I think I posted pictures a while back in the rig pictures forum.
