Where can I improve?? WHIR

[chcbb]

In a high-scoring 8-team Yahoo PPR league .... I seem to have decent matchup every week but 3 out of 4 weeks have gotten creamed. My top RB's are solid, but often I only get one good performance out of my WRs and Flex (2 spots) and the rest of the guys underperform. Should I trade up for a more consistent WR? Don't really want to get rid of AP or McFadden... and the stock on my other RBs is pretty low right now. What WR could I maybe target for Gore+Decker/Nelson? Any suggestions on moves to make are appreciated!
