I've been using Roto Grip for awhile, and the equiptment is great for my game. As you see I am lefthanded, and everything doesn't work for me. This equiptment is perfect for my game. I'm a tweener with good speed and pretty good revs, not overpowering, but use the lane and condition for my benefits. I wanted a ball to go longer than my Fuel and Global Assault with good hitting power. My Pro shop operator and I came up with the Pearl Silver Streak. At first the jury was still out on this ball, because I only used it when the other equiptment and conditions started being to much. There were times it would look great and other times it didn't. The scoup on this ball was it is a nightmare on the wrong condition and this is true. I bowl in two houses. One with wood lanes and the other with synthetic lanes. Being somewhat puzzled with this ball I polished it a little more, but hadn't used it until last night in my synthetic house. God gave me notion about this ball, in the way of trying it first instead of waiting till late in the night. I glad he spoke, and I listened. I am an approximately a 172 aver. bowler( struggled this year and coming back now), and up until now my highest series was 686. Last night I shot my first 700 series 743 to be exact(234,256&253)each game of which could've been a 300. I'm learning to deal with nerves. On the right condition this ball is a monster. Mine is the pin is about 10 o'clock label shifted and cg stacked
On the right condition I would rate this ball a 10.
