I bought a NVS when they first came out. I loved it out the box, bowled great with it until it died, wouldn't hook 3 boards if you rev'd it with 2 hands and were throwing on dry lanes.
Well, I was looking for a ball with that reaction and remember this thing sitting in my closet in a box. I took it to the lanes that night and the thing hooked more than most of my current equipment. It has since earned a spot back in the bag. I think it's a mixture of sitting for a couple years and me cleaning it with the powerhouse gel but whatever it is, I am glad.
