no poly, hybrid or otherwise, is likely going to last you over 20 hours without irritating an already sensitive arm over multiple stringings. i would accept that as an inconvenient fact and either adapt to non poly or restring more often than you like to in order save your arm down the line, but it is of obviously your call.
in addition to the swift and ghostwire @arzmentioned, you might want to look into isospeed cream, which can still start to feel harsh after 15 hours or so.
