Which type anchor tattoo is better?

Bruce or Plow, but only if you get a windlass tattoo on the other
shoulder.

I heartily agree with the Bruce/Plow recommendation, but would you recommend
an all-chain or chain/nylon rode tattooed across the back from the windlass
to the anchor? And what scope would you recommend for the rode tattoo?
Horizontal or vertical capstan for the windlass? So many details to
consider for a voyage of this magnitude.
