My experience, a narrow hone does not really help much with problematic blades. As Dylan stated I find that a narrow stone will help being more careful with the sroke, but for me that is all it does.
I hone everything on regular size hones, and only occasionally go to narrow side of my norton 1k, and a coticule.
I have one of those 1x5 thuris and although it gives very good edges I do not like the narrow size.
