I'm easily sub 20 at the moment. I average from 16-18 seconds. I'm currently learning full OLL (42 algs now) and trying to use X - cross and edge control in my solves. I have no idea how to preserve a pair or how to make X -crosses. All the X- crosses I make are mostly by accident or really really easy and usually occur about once in 500 solves maybe.
Could anyone give me some advice on what I should be doing and how I can improve overall?
Thanks heaps
