36t with Apex long cage RD

My bike (a Motobecane Fantom CXX from BD - don't knock it 'til you try it) came with a full SRAM Apex (if it's good enough for Alberto Contador, it's good enough) gruppo and a 32t lowest cog. I would like to switch to the 36t to help push my 280lb frame up the hills in and around Seattle. I have heard that this is possible without switching to an MTB derailer by only replacing the cassette and possibly the chain. Sheldon Brown says that manufacturers routinely understate RD capacity and that it is possible to push the envelope a bit. I've read of people running these very components online, but of course everything you read on the internet is true, right?

Has anybody been able to pull this off?

If it were me, I'd give it a try and if it didn't work well enough, I'd just get a SRAM X5 10sp rear derailer.

I have the Apex short cage and bought 11-26 and 12-32 cassettes but I have not tried the 12-32 yet (I live in gently rolling country and haven't needed it yet).
