Titleist's ‘next generation' of Pro V1 and Pro V1x balls took centre stage in Orlando, with Titleist claiming to have improved the most-played and best-selling golf balls ever. Titleist says both models now have more durable covers, made from urethane elastomer, and by increasing the size of the core and decreasing the width of the ionomeric casing layer, the Pro V1's ball speed and ‘drop-and-stop' performance should also be increased. The four-piece Pro V1x also has a redesigned ionomeric casing.
