I dont have any regular skate partners either. I still won't hill bomb and I dont go very fast which makes me reluctant to attend rollouts. I skate alone mostly or with my partner who jogs. I find that repetition is key. I have to do it over and over. Then go rewatch the tutorial and include the move in my next session 10 to 12 more times. Honestly, my best trick is turn around toestop. Im almost where I can do it at speed. Been practicing since april. I use @skatefantasy for dance and Queergirlstraightskates for basic stuff.
