I have 22 more OLL's to go before I know full Fridrich. I am wondering in what order should I start introducing the fine techniques? I already do Pieces Stuck in Another Slot and Using Empty Slots intuitively. Should I continue doing these intuitively or should I learn algs for them? When should I introduce multi-slotting and mis-aligned pairs? COLL? VH and maybe ZB? Also, for multi-slotting and mis-aligned pairs is it possible to learn these intuitively and how?
