I gave up on responsive and put a bunch of square ads in. They work well on both mobile and desktop.
For the ads in my best-performing placements, I have too. I still use them in some spaces, but I've found that CPC rates for standard 300x250 unites -- which Google recommends for both mobile and desktop -- are about double what responsive ads were performing on my site.
Have you tried the 336x280 size?
