I don't think it's a bad choice. I debated doing this and decided to keep the quill style just so my bike looks retro, but I'm also not having a problem with it being comfortable. You can find the quill style in many different lenghts to accommodate you. I don't know the advantages of the threadless are over the quill. I just think you could find a quill that would get you the same riding position of the threadless to make your ride more enjoyable and retain the look you want.
