Preventing your dough from warming up too much does a lot to prevent sticking, and a pastry sleeve and cloth are also really helpful. I use a chilled marble slab, put the pastry cloth on it and the sleeve on my rolling pin (both generously floured), and I have no problem with sticking. Of course, you don't have to use a marble slab - there are some tips here on keeping dough cool. I think if you focus on that and maybe also try the pastry cloth, that should help. Good luck!
