My advice is to get a wing suit and jump it. I have over 1000 camera jumps and I rarely feel like I am using my wings during the jump. After seeing myself from a second camera person's video, it usually surprises me how much I am utilizing my wings. Just like everything else in this sport, it is a touchy- feely thing that you will have to do and develop your own technique.
It seems that you have enough jumps to be able to get into it pretty quickly. Try it out and the wings will end up being a natural extension of yourself as you jump more with them. Good luck and stay steep over the 4 way
