2 minutes??? WTF!?? that's slower than me xD
I don't even know how to pair the edges properly, and I don't have a 4x4x4... and I'll never get one... and I still have 1:13.xx single at competition ;D
I have never practised it... and will never do... the first day I solved it I also got some sub2 solves.. 2 minutes is crap
