Im wanting to find another way to do LL after transitioning to ZZ. Ive been looking at ZZ-b and ZZ-d but I dont know what way would be the best. ZZ-d looks interesting but Ive read that its impractical for speedcubing, but Im not sure if I should jump from OLL/PLL straight to ZZ-b. Im not sure if all of the algorithms that Ive already memorized such as sune and antisune will transition over. What step should I take?
