Yeah but what kind of hills are you riding? Im talking about 20% on average. I can start with a 11-28 and if its not possible switch to a 11-32.
I find it hard to believe there would be many 20% average hills anywhere but there might be so if that is the case go for the 32. I know of hills that hit 23% in certain segments but they are short in nature and momentum takes care of it.
