Several. Extended butterfly, Ayesha(All grip styles), Pencil, Bow & Arrow & Hand & Elbowstands. Pretty much any move where my feet or legs have to come completely off the pole & am completely dependent on my arm/hand strength to execute the move. I like the look of the inverted thigh hold & recently got it but it still scares me to execute & I still struggle with it a lil now & then. I even fell out of it recently (first fall in pole), which scared the bejesus out of me.
My husband spots me sometimes but I still feel scared. Plus, I feel like I'm not always going to have a spotter there, so I need to get it confidently on my own without a spotter.
For me, time is usually a factor, in other words, eventually I work/push through the fear when I hit a pole dead end ie: I can't progress further to other moves unless I learn the move. However, if its a move that I can put on the back burner for awhile until I am ready to work on it, then I do lol I also think having a crash mat will help & I plan on getting one soon.
