i have been trying oa for 5 months now(i live in orlando, fl so i have been riding through winter) i have tried hs oa 5, hs oa3, and ts oa 5. I haven't landed one yet. Once you figure out the rotation though the ts 5 is easier. The hs oa 3 you haev to liek stop you rotation because whenever your body goes oa it wants to do a 5(try oa on the trampoline without the handle if you dont believe me, you will always do a 5). On a hs oa 5 you have to make 2 handle passes so that makes it kinda hard. With the ts 5 you only need one handle pass, and the landing is super weasy. It's just aboyut putting all of the leements together.
As for going wrapped, i have never tried that. Not a bad idea.
Don't get discouraged, oa takes nearly everyone a really long time(usyually a month or two, i jsut can't seem to get it)
