I'm definitely not a "bump skier" although I do ski them with the 108s. While they are certainly not the best tool for the job, they are adequate for my purposes. My issue skiing bumps is that I have a tendency to sit back, such that when I am properly balanced and in a rhythm, I'm fine, even with the 108's. point is, its me not the width of the skis. What I really enjoy is powder and off piste so the mid fats are definitely better for that.
