I love the clean crisp lines of the stripes in a top-down sweater. It is so easy to knit a striped sweater when you are knitting from the top down. You never have to worry about the stripes not matching!
Above is the pink/brown and below is the brown variegated I have been using.
Drying your yarn in trees is absolutely the best invention ever. The breeze dries the yarn quickly but the shade protects the skeins from sunburn or bleaching. It's wonderful!
