Which prime lens for Asia? please help!

I have the AFD 20mm/2.8, 35G/1.8, 60G/2.8. I also have the Sigma 20mm/1.8 but this is too big and heavy and not sharp at f1.8.

Given only 3 prime lenses to choose from, I am tempted to take only 1 lens with me but can't decide whether to take the 20 or the 35mm. I think eventually the 35/1.8 would be most useful but I often find it not wide enough on my D7000. My fav focal length is actually around 30mm (full frame equivalent), so the 20mm is ideal but this lens is not too useful in low light compared to the 35G/1.8.

Perhaps the ideal lens for me is the 24G/1.4 but it is huge and heavy... sigh...:(

Any comments and suggestions welcome!
