I am really surprised to hear that your Rising Star did not work for you. This has been my go to ball for a while. I am sure that you are aware sometimes you may need to adjust the cover to get the reaction that you are looking for, I did. The Disturbed is just flat out outstanding, it has a nice smooth roll with a strong continuous arch, hits hard. If you are looking at another solid,this is the ball for you. I had a Defiant, and I didn't like it until I changed the cover. But I prefer the Disturbed over the Defiant, so I sold my Defiant. I also understand the new releases are hard to make a choice without seeing what they do. If you are not sure, then wait for just a bit until you can see them in person or until there are more videos, but the bowlers in the videos never throw the ball exactly like I do, so they are not as accurate as I would like. As for Rotos mid level balls, they are second to none. I have had most of my honor scores with mid level balls, the most recent with my Rising Star and Disturbed. The most important factor is obviously getting the correct layout and surface, and using the right ball that matches up with that pattern, with your style. I have the utmost confidence of the person I see for my layouts and ball suggestions, and that is my suggestion, to discuss it with your pro shop if you are unsure on what to get. Don't be in a rush, take your time and do your research, then you will be confident in your selections. As for the Soul, I don't currently have one, but from what I have seen, its a great ball. So if you really want it, get one - but check out all of your options first, you might fill a need with another ball. Either way you cant go wrong with any ROTO GRIP ball.
