Never a 5 iron !
i'd think a 7 or 8 iron would be the best. A wood is too flimsy and long. The graphite could break easier, longer to swing. etc. I'd defintely avoid graphite shafted clubs. putters are equally bad as i don't think their build quality is as rugged
I think a 7 iron would be it, very maneuverable, you can swing it quickly. steel shafted , still would do a ton of damage.
