first of all, the run-stop is used as a technique to counter the people who play backup all match. if you're gonna call out someone for run-stopping you need to also call out people for backing up all match.
One technique feeds the other. Also brad is right, you call out brad you have to mention guy and majin as well because they do it at times.
second neither of these techniques are againts fpr, ethically you should watch how you use them but if someone is playing back up all match againts me... well i'll tell you what i will close the gap on him again one technique feeds the other.
as far as Aj goes, i agree the boot does not fit you it is a power move and your entire moveset if more tech/agility sure you can od a few strong moves but a one footed boot that just knocks the crap out of someone who is bigger then you does not fit. edge would not be able to big boot undertaker or batista. so i cant see aj big booting kage or cross. edit brad pointed out edge did the big boot to taker at WM so cant really argue this point anymore.!
and bold it think nate hit it on the head, if you bold have an option to pick a move that looks correct or a move that will offer you an advantage you will choose the advantage move instead of what looks right. sure one or 2 moves for "games sake" are ok but you should really re-think why your choosing the moves you pick.
