My 2c: even if Classic colors are more than right, I still prefer the more paler Retro, but please don't ask me why... (^^,) it's just my personal taste, that's it!

About latest settings Vs older ones: despite the fact I have a perfect color vision and my monitor (actually, a 55' LED HDTV) is well calibrated, I was not able to spot any difference, even when zoomed in... maybe it's my old age, the late hour, don't know... (xx/) so, the only thing I can say is: go for what YOU do think it's better, because frankly in this instance I can't be of any help!

After all, I like all your SW color regrading, so I'm sure we, final users, will be more than happy with the final results! And, I'm happy you decided to do also an AVCHD version this time - did you think about a complete BD-25 (or BD-50) version with menus and chapters?
