I have a #7 and really like it alot. Buying one had been in the back of my mind for several years. I just always managed to talk myself out of it. Really sorry I waited so long, I will not be without one now .
My #7 rides easy in the pocket and the handle is comfortable in the hand. I really like the size of it. That being said I would rather go a size bigger than a size smaller. I think that a #6 woud be a ltttle small, at least for me, so if I couldn't get a #7 I would choose a #8.
