Every time I try this trick I fel like I am doing it right but the slack only follows once (or not at all) then twists and tangles. Any suggestions? ???

You probably need to adjust your string tension. Also, just work on keeping it one fluid motion.

yeah it happens. make sure you practice the motion. dont make it go to fast or too slow or else the slack will get messed up

well sometimes the yoyo just spins out. Am I supposed to turn to my body or something?

Yeah, the reason it dies is because the strings hit the side while you do the trick. Try to line them up more.
