I have a HUGE problem with magic drop. Every time I do it, I get a knot. Please help. 
I need help with which string to land it on and how to help it make it land on the string more.
Watch this video, it helps a lot.
Something that helps me a lot to hit the back string, its on my throwhand pointer when I hit the string, I hit it with the middle of the finger.
;D thank goodness i finally figured it out i just hold my thumb almost strait up to do it
this helped alot
For trying to land it on the back string, it needs to land on the string attached to your throwhand finger. If you want to see what it looks like, start from a trapeze and pop the yoyo up. Undercut the yoyo as if to land in trapeze and bro, but land on the back string. Besides the wrap around your throwhand, this is what a magic drop is.
