Hi. I avarage about 17.5, and I want to be sub 15 by the end of July. I have efficient f2l, good cross and fairly good LL and decent lookahead, I watched jperm's sub 15 vid and he mentioned cross to f2l transition. I have been doing hand scrambles for the last 2 days and predicting where the first pair will end up in and sometimes solve the pair as well if I get an easy cross. But today I went back to solving and for some reason I can't even predict where my pair will be. Should I continue practicing cross+1 or should I make better lookahead.
