I have 11/32 cogs and they work fine with the stock SRAM DR. If you don't need the extra low gears often and the FR continues to be an issue you can take it off and manually shift the chain from one chain ring to the other. I had this set up on my Brompton for climbing and although I am not using it now it worked like a charm. A side benefit is you lose a little weight from the FR and cable.
