Qxs, J8s, etc. On the other hand, its much harder for a suited connector to hit this flop (he can't have 76ss,87ss, T9ss, etc. Because of this, a Ts7c3s flop is better for BB). And because its possible BB could raise the flop with a fd, while BU is always betting them. In other words, BB has less flushes in his range than BU.
