Dunks in Slam Dunk Contest

Now i don't want to look like a noob or something. But i need some help. I read as many threads as i could but i couldn't find an exact explanation. Now i managed to make some cool dunks on PC, like under the bum or behind the back, but that's all, i didn't even do the double under feet one. I use a keyboard, i know that i only have two types of alley-op throws and i know how to use them. But i need some help with some hard and cool dunks. My current keyboard is set like this:

bind K_4 PLAYCALL4
bind K_3 PLAYCALL3
bind K_2 PLAYCALL2
bind K_1 PLAYCALL1
bind K_DOWN DOWN
bind K_UP UP
bind K_LEFT LEFT
bind K_RIGHT RIGHT
bind K_Q BACKDOWN
bind K_A CROSSOVER
bind K_S PASS
bind K_D SHOOT
bind K_C TURBO
bind K_E FAKE
bind K_LCTRL DIRECTSHOOT
bind K_W DIRECTPASS
bind K_R DEBUG2
bind K_SPACE DEBUG1
bind K_ESC PAUSE
bind K_Z CALLPLAY
bind K_B R_UP
bind K_B R_DOWN
bind K_B RYAXISCHANGE
bind K_F R_LEFT
bind K_F R_RIGHT
bind K_F RXAXISCHANGE

With these controls, what can you suggest that i can do? Thanks in advance

do you have ppjoy?
well you dont need it anyways XD
just do this:
hold turbo and press the dunk button at the 3 point line, then press the dunk button again to do the jordan cradle.
^auto 50^
another one is a cartwheel and double through the legs. to do this hold superstar trigger and at the 3 point line press the shoot button and then after the cartwheel press shoot button again to do it. again this is a 50
here is another one its not always a 50 but it gets you higher than 45 if you do it right:
this time hold superstar trigger and press dunk button for the gather but dont start where you normally do, start a bit further from the 3 point line because this is gonna be from the free throw line XD so somewhere there press the dunk button and then wait 0.5 seconds and press the block button to do elbow hang and when you press the block button try to hold it as long as you can but not too long. the longer you hold the longer you will hang and the better your score

Okay done all those I especially love the Cartwheel + Double through the legs, awesome dunk...But i want to do an Armpit dunk as well and many more *drool*

well the armpit dunk is basically elbowhang cause if you hold it long enough its called "armpit"

lol cool cool
