I have a IMMORTAL SOLID, 16 lbs for sale. I've tried different cover prep, two different drillings. The ball is a TURD. It's decent straight up the boards, but you cannot swing it. I'm SERIOUS!!! I tried to sell it in town, nobody wants it. The pro shop in town won't recommend VISIONARY equipment because of that ball. (HE TRIED THAT BALL AND SAID IT WAS A TURD ALSO.) I have a CENTAUR PARTICLE I use in tournaments. LOVE IT!!!
