I enjoy tapping out someone as much as the next guy. I have to admit though, I think sweeps and reversal are more fun. Maybe it's like hunting, I like the experience of hunting more than I like the kill.
I also like Total hold downs, a position where your opponent's limbs are so wrapped up that they can't move or defense themselves. I dont have any siblings, but I feel like the total hold down is the adults version of sitting on your little brother's chest and arms and poking them him the forehead with your finger.
