the red distressed reissue in spring 2011 is pretty dreamy. (i am generally not a fan of distressed reissues other than black) the purple lamb is nice too
I love my anniversary black 226... However, I also love my metallic pink 227 from 08A...
I would have a really have a tough time choosing between the 2.
I would like to add that a close favourite would be the 07 navy patent reissue. That year, the patent used is crackled/distressed and it leaves no fingerprint marks when handled. As it is patent, it is waterproof and in the event you are caught in light rain (so far i havent), it repels water. For the calfskin, I am pretty sure if leaves water marks and so I get very paranoid carrying my grey out.
