Jimlim... honestly... the angle of bounce thing. is a CHILD play.
give me 10 minute to draw.
Added on August 13, 2012, 12:39 amJimlim, are you familiar with a "Bouncing Ball" law of gravity/bounce (if such law existed)... when u throw a ball off, 90degree down, the ball bounce back 90degree right? so u if throw is 120 degree down, it will bounce 120 degree back up (it Wont bounce 90degree, dont say spinning ball laaa)...
the logic apply to BOUNCE. so here you go with a lapsap cheatsheet from me....

if you look properly, u notice that, where ever ur subject is, u always bounce right in (directly) middle of between u and subject? see the idea?
YES, IT IS THAT SIMPLE. period.
all you need is bounce right in the middle of between u and subject.
you dont need to be PRO to learn.
you need to be PRO to teach 
so what so special about the skill to adjust the angle?
