The Vise-IT is another great interchangeable Thumb system available to bowlers to allow the same great feel in every ball you throw. Chris Barnes uses the Vise-IT: "The VISE Interchangeable Thumb allows me to have the same feel in every bowling ball I own. I can bowl with confidence, plus I can quickly move it to another ball without any tools. I am using "IT", you should too".
