I think its hard to rip body parts using grabs cuz you cant wind and get enough speed.

YOU DO NOT HAVE TO READ THE FOLLOWING! REPLAY IS SELF EXPLANATORY!!

Well after the kick in my replay (at bottom) i saw his head and grabbed it. After the attack, i like to jump around (i donno why) so i did a flip. Then i got so much speed the force ripped his head off. give advice

This replay is worse anything you have posted so far.

Pardon if im wrong, but arent decaps supposed to be HEAD only?
Because it seems you have also ripped uke in half.
Also, its alot easier to dismember with grabbing, so that could've been pure grab dismemberment besides the torso.

really? ive neva broken a joint with my bare hands.

ok..mos 0_0 you couldve decaped him without grabbing and grabbing can dismember

even though you were able to knock of the head so easlier (which is easy because its the most its the only part of the body sticking right out) you must also be able to do madman moves Madman moves are moves that are fast and rapidly dismember you and you're opponent at the same time.
Like So:
(note, its not as fast because of the lag created by the dismemberments.)
