Any BURTON binding will fit... it does not necessarily have to be an EST binding, although that is highly recommended. The board will come with special baseplates that fit other Burton bindings so you can mount them on an ICS board. The new X8 is pretty sick, but you can find something else just as legit from another company, that way you can keep your Forces... which by the way are killer bindings. Check out board like the 09 Forum Eddie Wall or the Ride DH, both will be comparable for the most part. Also the Capita Inddor Survival is a little stiffer than the X8 but it still jibs like a champ. Those are just a few suggestions.
