The OGRE-Urethane core takes the core from the OGRE line and encases it with a lighter spherical wrap. The core is then covered with a Hard Urethane coverstock.
As always Visionary strides to keep its quality to the highest of standards, BUT, due to the extremely violent nature of the chemical reaction when pouring these balls, some small porosity may result. This is nothing that would alter the balls reaction in any way. Unlike the rest of the OGRE line, which is powered by a symmetrical, dual density core design without a wrap – the OGRE-Urethane’s heavier cover created a need to lighten the overall core weight to keep the total weight the same. This lighter wrap (found only on the OGRE-Urethane) also counteracts the higher density cover to keep the ball RG virtually the same while slightly increasing the differential. This produces a hard urethane ball designed for spares but with dynamics that allow it to perform extremely well on drier lane conditions (or for people with higher revs).
