I switched just because 19x19 is classic, and I heard that that was about the cutoff point where I could be competitive on 19x19 with a 9-stone handicap. Although this is against gnugo - I think SmartGo is significantly stronger and I don't know how its 19x19 play compares. I know that when I play SmartGo iOS in its adaptive mode, it doesn't even let me try 13x13, it's not unlocked yet. :)
