Tanking

I've got six hundred yards of Lion Bran Cotton Ease (in terra cotta.)
I want to make a sweater. I've narrowed it down to (rav links):

• Tube Toporini
• Thira (Thank you mujercita)
• Pretty in Pink
• Tswirl

Maybe "narrowed it down" isn't the correct term. I really can't decide. I'd rather do the Tswirl in a gray and wear it over a long sleeve shirt in the winter...maybe do Thira as a fall "over a shirt" sweater, too. This leaves me with Pretty in Pink and Tube Toporini as the top two. But maybe I do want Tswirl for the summer...

Argh! Someone tell me which one to do!
