Edit: anyway, methods:
CLL, EG-1, EG-2, TCLL+ and some of TCLL-, Ortega (If I know I'm gonna get an OLL skip) and some other random tricks. So basically everything
I average somewhere between 4.5 and 4.9. I don't do enough 2x2 to know what I actually average. I use Ortega, with a couple of OLL skip tricks (WV with 2-3 corners oriented) and a few CLLs that I rarely ever use (the only one I really use is R U R' U R U L' U R' U' L).
