I agree, I am a big fan of colour shot in 1x1 and have made the switch. I get way better resolution plus you can desaturate your RGB and use it as additional luminance (not sure it makes much difference if any though).

With my refractor there is quite a big difference in resolution that is noticeable in images between 2x2 and 1x1 in RGB. It is more apparent with shorter focal lengths - something you won't have to worry about!
