The answer is very simple, use the pause and blind trick. First, practice doing the cross blindfolded until you can do it that way within a 15 second inspection time. During F2L, when you ID the pair, don't solve the pair; stop turning. Examine all the pieces and figure out the next pair even before solving the first one. You should know how the F2L sequence or algorithm affects the pieces you are not solving, therefore it is possible (given enough time) to see 2 pairs into the future. Once you are sure about the two consecutive pairs, close your eyes and solve both with eyes closed, then repeat for the next 2 pairs. This process will be very frustrating and time consuming at first, but as you improve it will only take a few seconds of pause, gradually less, until there is no pause at all and you can see far into the future.
