The vote as of yesterday was 15 for Metro and 2 for the Tea Leaves Cardigan, so I'll be starting Metro! Since it has 3/4 sleeves and the Tea Leaves has long sleeves, the Metro will probably be wearable first anyway. Both styles will fit my wardrobe, so once I finish Metro, I'll knit the Tea Leaves Cardigan.
There were several questions asking what yarn I was going to use. The yarn I'll use for Metro is Jaeger Shetland Aran in black. I bought a huge amount of this when it was discontinued and while I wouldn't ordinarily use such a dark color for cables (it's hard to see cables in dark colors), this sweater isn't heavily cabled and the alpaca in the yarn adds a little bit of shine, so I think the cables that are there will show up just fine. You can see in the photo of the ball of yarn above that even though it's black yarn, I didn't lose any detail photographing it (so it won't be like blogging a black mohair sweater in process).
