i've never played with isospeed pulse before but i have strung it up a couple of times for players and for a poly it does seem very soft and you will struggle to find many options that soft in the same gauge. the only 16 gauge poly i could find that comes close is gamma zo tour 16 which seems almost identical in stiffness and tension loss. otherwise, strings like babolat pro hurricane 17, head sonic pro 17, pacific poly soft 16L and tf red code 18 are reasonably similar
