well not that you have to use my advise or anything(and really im not insulted or trying to prove a "grand point")but one more thing i guess i should note is that if you do go down the physics engine road, you also wont have to program the grenades bouncing off a wall or other geometry as the physics engine will do this for you.
just something else to consider in deciding what road to travel.
