I also use home made, 1/8" bungee from west marine. I zipped tight it at mouth piece. I have seen those IST type of necklace. I haven't use it myself. From the look of it, I don't know how secure they will be holding on the 2nd stage. The last thing you want is to have the 22" octo come off from your necklace.
