Introducing Isospeed Grey Fire ! This follow-up to Black Fire offers impressive comfort for a co-poly. Built with low-friction Liquid Wax technology, Grey Fire snaps back powerfully through impact for extra ball rotation. It also benefits from Isospeed's Triple Heating Technology , which helps the string flex more at impact for added comfort and pocketing. Big hitters looking for a comfortable and spin-friendly poly should give this one a serious look
