Ok so i've been cubing for a few months now.I am totally hooked. i'm learning Fridrich and i've got pll/oll down great. but f2l is giving the most trouble. it slows me down sooo much. i think it takes me around 35-40 seconds just to finish fridrich f2l. it takes me 25-30 using plain beginners f2l. im averaging about 45 seconds and my pb is 34. any tips? thanks a lot.
