if you've not got a load of cash to burn get your campaign in order on msn or yahoo then move in hard on google when everything is converting nicely. doing the quick maths you should be able to cut your bids in half with a few days history so if you're not getting above half your initial bid on G forget it and work harder on your campaign to bring it up.If you can't play with the big dogs step down from Google, to MSN and Yahoo and get your dick wet. You should find more reasonable bids, but less traffic.
I think there are two Wu-Yi offers. One high paying and one low paying. The difference? I don't know but if I were to take a guess I'd say shaving percentage. I think one has a higher rebill as well.

And today, bids are down about 1/3, and ctr is 4X better..
personally i'd drop wuyi, thats been heavily "adjusted" for returns already
