Start with the grips of the mirrors if you're going for visual impact (they'll be noticed faster than pegs or a layback plate).
Note that the grips you're looking at are really comfortable compared to the OEM grips. Also note that those mirrors (and most other decorative mirrors) don't off the same view as the OEM mirrors so you may also have to get offsets.
