Think twice before you invest feats on grappling or tripping tricks. Those moves are moderately effective against medium-sized humanoids. But not that much effective against larger, stronger monsters. And there are critters you cannot grab or trip at all (or you don't like to try). Oozes, incorporeal undead, something burning, etc. Thus, those maneuvers are very situational. If your DM use a lot of humanoid foes, could be a good choice. If not, could be almost useless.
