The New Design for More Speed
                                                    
                The new TSi1 Hybrid  by Titleist builds off advances made by the TS1, such as launch and spin, inside a newly-designed head that produces more inertia and ball speed at impact. The TSi1 Hybrid  comes in at about 20g lower in weight than other top hybrids, helping to produce optimal mid levels of launch, spin, and draw bias.
