OOC: Here is what I propose for a throw opponent: Throw Your Foe to the Ground: This works just like a trip attack except that you don't make an initial touch attack (because you're grasping your foe already) and you and your foe make opposed grapple checks to resolve the trip attack. If you win, you and your foe fall prone in the space you both share, but you're still grappling. At your option you can take a -4 penalty on the opposed check; if you win you break your foe's hold on you and you throw your foe to the ground in a space adjacent to the space you formerly shared. (You stay on your feet.) Your foe's movement does not provoke attacks of opportunity, nor does it count against her movement for the current turn (or her next turn).
If you lose the opposed check, your foe gets a chance to trip you by making an opposed grapple check, just as described above
You can make a strength check to throw your opponent farther... per 10ft distance of attempted throw make a strength check; opponents weight (including gear carried) divided by 10 is the DC of the strength check. ie... a 40lb character would require a strength check of 4 per ten feet, so DC 8 for 20 feet. Remember must add weight of gear carried and make the attempt at -2 if opponent attempts to stop you.
