Well, if you go with Rilla's option of a stalemate, it might be fairest for the bear to throw the turtle as far away as possible just becasue 
1. Sukoh has taken more than his fair share of damage
2. Khan's turtle is slow, so he won't be coming back, and Sukoh is injured. If it were the other-way around it would be a victory for Khan.
3. I believe Sukoh could throw the turtle much further than Khan could throw the bear, just because its so heavy.

Up to you guys though I guess, and I haven't read the fight so it might not be possible.
