Another newbie

I am also new to this KAL, but purchased the pattern shortly after it came out. I am trying to get some other projects wrapped up before starting this. I also haven't decided on my yarn yet. I'm considering KnitPicks new superwash worsted weight yarn, Swish, as I have two small (translate: messy) children, and a husband who does almost all the laundry (translate: machine wash only). Mind you, I'm not complaining about either, but rather trying to create something compatible with my environment. Anyway, has anyone heard anything about Swish? I'm curious as to how soft it is, how it holds up after washing, etc.
