What percent of your visitors do you acquire from Adwords, Yahoo SEM, and adCenter

When i first started I had campaigns at all three, it was honestly too much to manage. I dropped down to just google and have seen good results. Now that I feel I have a handle on google I might wanta give the others a fair try.

Total paid visitors: ~10,000 / day
Google: 100%
adCenter: 0%
Yahoo SEM: 0%
