I'm a little surprised at the question. You've done backflips on the tramp; you can do 7s and corks so you're not a noob; and there are vids aplenty on youtube.
What info are you missing? Or are you maybe looking for comments from people who can remember the first time they tried it?
I just wanted to know like where I can try it with the least risk. I did not know what the best jump would be like a QP something super popper or whatever else. Trying a backflip just seems alot different from the stuff I am doing now. I just don't want to land on my head haha I know I can do it if I commit I just have to go for it then I'm sure it's pretty easy.
