Well I am always more than happy to be pointed towards good guides on the subject as I think there's no such thing as knowing everything.
At the moment, I'm still practising intuitive F2L and I'm certainly getting better at it, but I do wonder if it's impacting on my speed just figuring the puzzle out for F2L rather than simply identifying patterns and repeating known algorithms?
Reason why I say that is because under LBL, I apart from the Cross and F1L corners, the rest is all just straight algorithms and once learned I was able to basically solve very consistently in speed just through recognition of patterns and responding with learned algorithms.
With F2L, I'm finding I constantly have to stop and actively think about the solution for each slot and it's probably chewing up a good 2/3 of my solve time, even with still employing beginners LBL to solve the last layer!
