Too many options, not enough ideas

I'm knitting a lace cardigan from some beautiful Habu Tsumugi Silk (in colour 38, a purply-red) I bought from I Knit London a few months ago. I looked at it for a long time, and decided I wanted a lightweight, wear-everywhere, match-everything casual cardigan for warm weather. Basically to wear over dresses and tanks and stuff. But not as fancy as the black silk Horseshoes Cardigan.

I've finished the back:


I'm halfway through one of the fronts, and am at a decision point: what kind of neckline do I want?

As you may have noticed, I'm quite fond of deep scoop necks (see the Horseshoes Cardigan, the Silk Garden Scoop Neck Pullover and the Scoop Neck Tee). In this case, however, I want to be able to wear it open and closed without the sides flapping about too much.

Options:

• I think probably a normal crew neck (something like the one on the Synergy Cardigan) is the easiest choice, but kinda boring.
  
• A V-neck is the next obvious choice, but, again- eh. V-necks look alright on me, but boring again.
  
• A really deep v-neck, starting below the boobs and going steeply up to the shoulders?
  
• Or a V-neck starting from below the boobs, but stopping a few inches before the shoulders, from where it will go up straight to the top of the shoulders. So it looks like a scoop neck, but with straight lines at the front instead of curved ones. A sweetheart-ish neckline.

So, as I said, I'll have to make a decision on which neckline to do soon. (One of the reasons I knit things in pieces like this is precisely because it gives me time to think about these things. Also, so I can estimate how much yarn I have vs. how much yarn I need.)


I can't get a good picture of the colour of this yarn. It's purpler (yes, that is a word) than the picture above.

After I decide the the neckline, my next question will be what to do with the sleeves.
