For the Nanners...

I want to start another sock tomorrow and can't make up my mind which yarn to use. #1 is Socks That Rock - Love in Idleness #2 is Socks That Rock - Rose Quartz
#3 -- Socks That Rock - Lovers Leap
#4 -- Socks That Rock - Lucy
#5 -- Lorna's Lace - Valentine
#6 -- Joslyn's Fiber Farm Twinkle Toes - Montego Bay
#7 -- Koigu - ??purples??
#8 -- Mountain Colors Bearfoot - Obsidian

So my fellow Plurkers...which one for the Nanners? Post your choice in the comments. And if you don't Plurk, why not?
