Because uprights fuck with my wrists, i do my heavy sets with the dumbells and then hit upright rows with light weight. My traps are definately my best bodypart and it began with me altering the way that I shrugged the dumbells. Instead of holding them out of the side with the ends pointed at the mirror, I bring them in front of me, ends pointed at one another and do a sort-of quarter upright row/squeeze/shrug. It's killer. Give it a try.
