Yours is not at dumb question at all, furashgf.
The real issue is having the right gauge strings for the particular instrument you are playing. As jeff writes, light-gauge strings are an absolute must for most vintage Neapolitans— new ones, too, although there has been a definite tendency amongst modern luthiers to brace their tops so that they can bear the weight of medium-gauge strings.
So, what instrument are you playing? Also, please bear in mind that many light-gauge strings (as they are made expressly for Neapolitans, with their characteristically short, 13-in. scale) may not work as well on a longer-scale instrument (vis a vis intonation, evenness of tone, etc.)
Many, many possibilities...
