Hey speedcubers, i need some of your help. I really want to get faster with f2l, im wondering how people do it in SECONDS, i know they inspect xcross, but how to get faster?
Maybe that's a good read for you: https://www.speedsolving.com/threads/how-to-get-faster-using-the-fridrich-cfop-method.6085/
It's a pinned thread so you can visit it over and over again, also your question is better asked there.
Anyway, without more information I can only say practice. Get confident with your solutions. Also no need for XCrosses yet. Try to do stuff intuitively and later on find good algs.
