When inserting the last F2L pair, if you know edge orientation, you can guess the OLL Case. I use 2 Look OLL so its pretty easy to guess and it goes in a flow. But in full OLL it can be tough in the begining but after you get the hang of it, it will be easy. Look out for corner pieces, and then look for edge piece and try to guess the OLL. In PLL I normally see 2 opposite sides and then by idea I solve it 
at what pace do i turn the cube in order to look ahead - ANOTHER QUESTION.
how to look ahead during oll, pll...
i need speed... i love cubin'
