This can be a difficult transition for some people, fortunately for me I found mistys, flats, and corks to all come pretty naturally after I had backflips, frontflips, and spins down. For mistys just think about throwing your shoulder forwards across your body (it helps to reach your hand for your opposite foot as you throw). Flats and rodeos I found to be the easiest; basically start with flat 3's, very similar to throwing a backflip except you just have to choose a shoulder to open to the sky as you take off (This will set your rotation slightly off axis), personally I also found that by taking my hand opposite of the shoulder I'm throwing with and kind of grabbing the back of your thigh helps too, a lot of people also find it helpful to reach out and grab japan. After your get flat 3s just open a little bit more and keep looking for the flat 5, it shoulder be very natural. One thing that is extremely important to note is that where you are looking will affect your rotation, especially when starting to learn off axis flips. Make sure you are consistent with the way you look and set your shoulders. Corks can be tough, instead of thinking of it as an off axis backflip like flats, I think of it more as a spin that you set off axis. When you are initially setting up for a cork 7, take the arm opposite of the way you are spinning and pretend to throw an apple (so take your right hand and throw an apple up and to the left or vice versa if you spin naturally the other way). Head position and where you are looking is very important when learning corks, it will probably take a few tries of throwing regular 7s and slowly progressing your way to more off axis spins until you get corks. For lower spin corks like cork 3s and 5s, pretend that you are throwing you feet up a wall. Hope this helps
