Have you thought about using the drop handlebars and raising them up to make them more comfortable?
also you might need a wider drop handlebar due to your statement about riding the corners makes your hands turn in...

I know of one guy that said that he raises the handlbars so that the drops are at the same height as the seat... the only problem with that is you might have to spend some money for cables because they are unlikely to be long enough for you to do that... (I have thought about doing that myself actually but I guess laziness has kicked in and I don't find my current setup uncomfortable...)
