WP Theme with 728x90 ad space

My website starting getting more traffic and earning more on adsense, and they sent me couple of messages saying: "Our system analyzed your site, website.com and found a great opportunity to increase your AdSense earnings. We recommend that you change your 468x60 ad units to 728x90s on website. com. "
They also say I could see a noticeable improvement on the eCPM's, as many others have.

Currently I use Heatmap Theme and the only place for a 728px ad is very up high which i dont like. What's a good theme to use this ad?
Thanks.

Hey that looks great! But are you sure a 728 px wide ad would fit in the main content area...homepage and single pages? It looks narrower than that.
