The best tutorial I've seen in my opinion is actually Erik's 5x5 tutorial. At the beginning where he starts out with 4x4, that's how I edge pair.Wow, I REALLY need to work on my pairing. Are there any advice ? tutorials?
PJK, my 4x4 locks up a lot too, and it's hard to grip, sometimes sides slide a bit if you execute an algorithm. I hate it.
