HX Diablo Tour golf balls offer an exemplary combination of distance of the tee and pinpoint control on approach shots. Our Power Reaction Core is firmer on the outer edges and gradually gets softer on the inside, creating less spin off of driver shots and more spin when using shorter irons. The thin Ionomer cover increases spin even more around the greens for aggressive shot-making and improved short game control. HX Diablo Tour combines all the best elements of the HX Bite for spin and the HX Hot Plus for long distance in one 3-piece performance ball.
