Hard for me to imagine the rough terrain affecting the belt. I'd probably worry more about the hub.
Gates offers two lines of belt drive systems. I'd get the CDX high-performance parts for your application. Everything is compatible, but the CDX has, for example, steel rear sprockets versus the mixed plastic and steel on the other line. You probably know all that already.
