Hike mode angles

I'm going to upgrade my touring bindings this year and am facing a dilemma. I want to break the bank and go for the salomon shift bindings. However, the only thing that makes me think twice is the fact that the walk mode risers are 2 & 10 degrees. I am currently using the duke which has 0, 7 & 13. Any advice on how much it would suck to tour on flat with 2 degree angle. Also do you think 10 degrees is enough riser for steep climbs? Perhaps I'm just overthinking it.
