So, when I'm solving F2L, finding the Edge and Corner is very important. But what you must understand, is that once you have the cubies located, you have to pair them up. I have found that it is easiest to look for a corner on top and then find it's edge. This is not the best for look-ahead, but when the corner is on top you have a relatively easy case to execute and pair. Granted I always go for easy corner and edge pairs, but when there are no easy ones to spot I resort to this. Now for me it's also helped to do one pair and then do the slot next to it, instead of have to fill two slots diagonal from each other. You can see I plan out my F2L very carefully. I want to know what you think.
